Following Rob's suggestion:

"... I'd much rather have a schema for these than wait on 
someone to decide to convert them. That could mean a device.txt -> 
trivial-devices.yaml -> device.yaml trip, but that doesn't seem that 
terrible to me. Then we at least are running schema checks on the 
devices and know if actual users have more undocumented properties."

Applied.

Thanks,
Guenter
