The firmware has an ABI to the kernel driver.  If it changes, both have to
change.  This has happened with, e.g., ipw2200 (which has out-of-tree

I have no idea if this ever happened to one of the drivers with in-tree
firmware.  But it is a very rare event, that much I have to agree with the
people who made this mess.

That's not how it works.  The way it works is that it can easily blow up in
flames if it uses the wrong version of the firmware by mistake.  Or (FAR
more likely) it just doesn't enable the device at all because it cannot find
the correct version of the firmware it wants (if everyone did their job
right and changed the firmware name when they changed the firmware).
