In what way is it annoying?

Most distribution people aren't even aware that drivers like tg3 and
bnx2 even have firmware.  In fact it's self contained and less for
them to worry about.

The correct firmware is right there in the driver, it's what the
driver maintainer tested as a unit, and everything.

It neither gets in the distro guys way nor causes any functional
problems.

It may cause potential legal issues, but that is another matter.

Distro folks do ship external drivers that have their own 802.11
stack, so this is a very good example in fact :-)

I think the modular vs. static kernel image is a better analogy.
At least with that I have a real choice, with this stuff I suddently
won't.

Regardless of what you or I think about these changes, the fact is
that there were definitely some areas of contention and even some
level of misrepresentation of these changes.  And given that, some
of us feel that merging this in right now was on the premature side.
