My sweet spot is leading a project from "no implementation spec but clear end goals" to a real supply chain shipping real products.
20+ years designing and building hardware, 10+ years building physical stuff in Shenzhen.

My backhand is OK but my forehand sucks. Grip styles for standard handles usually end up favoring one side or the other. I'm making a handle shape that's easier to get the blade angle right on both sides. Hopefully a couple more iterations on the 3D printer and then I can have a functional prototype made.
Things like suspend to RAM/disk working, GPU performance is reasonable, WiFi and disk speeds aren't slower than expected.
I don't remember much about my statistics classes but even if you're a 99th percentile driver can't you still say there will be a large increase in your own personal probability of a fatality if you jump from the car curve to the motorcycle one?
Framing is much more resistant to collapse once you put sheathing on it, a roof, etc. Before that it is easier to fall over.
A half built wood frame wall only supported at one end is like a wet noodle if you don't put in some temporary braces.
That's (historically) not the case for US B2B shipments. For those, DHL pays the duty as the shipment goes through customs and then sends an invoice after the parcel is delivered.
The carriers do already have practice ramping up and down for Christmas and Chinese New Year so it seems plausible they could absorb significant extra volume in whatever time it would take to negotiate the leases on the extra flights they use during those times.
For that matter customs processing also has experience managing the same surges.
I'd believe we might have some sort of own-goal planned for customs that could hang things up.
Your fast prototypes coming by air freight likely aren't routed through USPS at all unless it's the last leg of a consolidated shipment that's broken apart once it reaches the US. Those would be using some other carrier to get them from China to the US and then USPS only inside the US. USPS all the way from China is slow.
Paying ~$30 for express shipping through DHL (plus whatever the new tariffs end up being) will still get you those parts in 3-5 days to most major shipping hubs in the US, your suppliers will just need to start filing the export paperwork correctly.
These changes will likely have bigger impacts on cheap off the shelf parts from e-commerce places like Temu or AliExpress, who were previously taking advantage of both the de minimis rule and inequal international rates through USPS.
Your Chinese suppliers can still ship by any of the normal commercial express shipping carriers as long as they understand how to file export paperwork or have an agent who can do it for them. Previously this usually added 1-2 days to the transit time over shipping undeclared "samples". Last year DHL moved to a paperless system and that extra 1-2 days delay is probably going away anyway. They may have even done it because they saw this coming. People have been grumbling about the de-minimis stuff for a while now.
The makerphone was a learning tool and built to that spec. It wouldn't survive being carried around in your pocket, for example, but it was fine for teaching you how to program and how a phone works.
If we're getting technical it is a mobile phone, just not a cellular phone. A cellular phone will work anywhere it can get a compatible cellular signal and this will work anywhere with decent WiFi.
We've also specifically avoided adding many additional features while the calling and texting was brought up, so you aren't wrong on the philosophy, maybe you just bought yours before the work was done.
You can enable logging errors to a serial console. We don't add that by default because it slows down the OS. My email is in my profile if you'd like me to walk you through how to enable that.
The back of the phone can be replaced with a custom PCB or breadboard holding your custom hardware. Pogo pins make a connection to the motherboard. The idea is you could carry whatever you end up making around in your pocket just like a phone once you're done, assuming you only put components on the inside of the back cover.
Disclosure: I designed and manufacture it.
There is also a way to restore the deleted info from a backup server once you have the phone back.
I made an ESP32 based phone that can send LoRa messages (among other things... the phone was designed to be hacked on).
The back of the phone can be replaced by a custom PCB, sort of like project Ara except accessible to anyone who can design simple boards. One of the boards we designed is a LoRa radio and the phone book/contacts in the OS has a built-in field for a LoRa address.
Joke, but also not a joke due to different market pressures on components like that vs. the high end ones.
