Does it? I assumed we'd be fine just using 0xffff (which I understood
from the spec to be reserved for development purposes).

That actually means "use 65535 until you've requested a unique id".

I'd rather use 0xf2d6 (a random high number) than 65535, even though that's out-of-spec.

I guess a
potential problem would be if this device is also used at the same
time as an experimental device that is also making that assumption,
but that'd be easily fixed by the developer who's doing the
experimenting.
