I added bzip2 as an exercise. But realistically, what would be wrong
with distributors deciding to ship /boot/config-$UNAME_RELEASE.bz2 and
saving a bit of valuable /boot disk space?

Even if people /do/ submit patches do do all of those formats, your
argument is based on the premise that having that ability is necessarily
bad. I don't think we need them, but I don't think it's a good argument
against this patch either.
