What was wrong became painfully obvious once I tracked the problem

Up until this change i didn't need to set deftxkey, it seems to have
defaulted to wepkey 1 which i did have set. It is an obvious workaround
now, but a note in UPDATING would have saved me about 9 hours of reading
commitlogs, building kernels and rebooting (on an old slow laptop).

If it doesn't violate the standard, could we make deftxkey default to
the lowest indexed WEP key that has been set? if not, could we mention
it in UPDATING and/or ifconfig(8) lest it bite someone else.

deftxkey has defaulted to an undefined state since 6.0. Perhaps you can show the specific case that is a regression for you.
