I used a Thinkpad for over a year without noticing the microsd slot on it. I think they are so inconspicuous that most people don't even notice them.
And what is the alternative?
USBA <-> USBC <-> SDCard adapter <-> MicroSD to SD adapter
Is that convenience?
Even if they gave away usb sdcard adapters for free, it would still be trouble to go out and get one. Or carry one around with me everywhere. Just another thing to lose. Another thing dangling out of my computer putting stress on the ports.
If I'm completely honest, I think it is more emotional than practical. This craving for hyper-optimization.
And even Apple now seems to be admitting that it was not a great idea.
I can understand dongles for tablets, but this is supposed to be a laptop, a somewhat general purpose computer.

I assure you you are in the minority on this.
MagSafe by the way is amazing. It has saved my old Macbooks more times than I can count. I've already had to get my USBC power slot replaced from tripping on it.
Having access to the ports is itself a feature. Having the peace of mind of knowing that you can go to the office or classroom and be able to use the projector or a jumpdrive, without having to worry about bringing the right adapters is a huge plus for me and I think most people.
