Good point.

Martijn Braam says: "It depends on the device, of course, but I don't think adding support for usb-serial adapters would be a problem. I already did that to test some things on the PinePhone. I guess enabling prolific, ftdi, and ch340 would cover most adapter cables. Unfortunately, it would be a per-device kernel tweak. I'm not sure how much devices have usb serial support built in already. The allwinner kernel only has CH341 support currently."

I suspect that a HowTo and some quasi-official encouragement might help to make this happen...
