I don't really see what you're trying to get it so I arbitrarily picked
this ...

I think "ROM patching" like in BT and 802.11 are two completely
different things. In BT at least you have a common transport to the
device, a more-or-less common command set (HCI) etc. None of that exists
for wireless (today) so trying to find common ground between firmware
(patches) for different 802.11 hardware seems completely futile?
