Exclude USB drivers from main kernel image?

Hi,
If I recall correctly from the /etc/devd/usb.conf discussion, decision
was taken not to exclude USB drivers from main kernel image (and leave
it to devd to auto-load them) because of timing in the 9.0 release
cycle.
Now that 9.0 is released, would it make sense to do this change in
HEAD and make the kernel image about ~290 kiBs smaller? Attached patch
does this for all USB drivers that can be handled by devd (except ukbd
and umass for obvious reasons).
Note that a very similar change has already been tested for several
months in Debian GNU/kFreeBSD kernels, with no observable ill effects.
