I agree.

In theory, those kind of files may be located anywhere, but in this
specific case, it is in /lib/firmware.
The firmware files could be moved elsewhere, of course, but:
1) /lib/firmware is the "standard" location for firmware files;
2) a binary-only tool can be used to load the firmware and could
expect it to be located there.

I think this would be sensible, as long as /lib/firmware is excluded, as
well as /usr/lib/firmware (in case of merged /usr).
