okay, i mean, that's exactly what my original comment said: this is only a problem if you buy cheap cables.

If some of your devices require a $30 cable and you use the same cables for everything, then you use a $30 cable for your mouse.

If you're buying a cable for a specific device in a specific circumstance than by all means get the cable that meets that. Then it's not a problem about "what is its functional support", it doesn't matter, that's your mouse cable that you use for your mouse on that desk. That's the monitor cable you use to plug things into that monitor. That's the dock cable you use to plug things into the dock.

For all the cables that are your flex carrying around places where you don't know how it'll be used tomorrow, get a good cable and you won't have any issues.

Yeah? I use a $15 cable for my mouse. And then when my mouse is done charging I put the cable back in the bag with my portable monitor, which the same cable also works for.

It's also only a problem if they overcomplicate power delivery design such that you need expensive cables.

They could have made it just DC +19V and GND over 14 gauge wire with a nice, outdoor-recreation-grade connector and called it a day.

USB power delivery doesn't need expensive cables. Basic 240W cables cost $3-4.
