I guess I'll propose this more formally, since nobody really seems to
have any thoughts on the matter and parsing radiotap is notoriously
difficult :-)

FWIW, especially with vendor fields, there's a problem today: these
always come more or less last, so you have to understand all bits before
them. This is also true for radiotap, but due to sequential allocation,
if you care about a certain field today, your software is guaranteed to
be able to read it in the future too. If your software cares about a
vendor radiotap field, that's not true since other new standard fields
may be inserted before it...

Speak up now if you do think it's a bad idea ;-)
