No more so than has already been done by supporting SCSI cdrom at all.

Which should actually be smaller than the flood of mail saying things
like "why doesn't burncd support my nice, standard-compliant CD-R?" In
fact, according to the documentation that comes with cdrecord, it
would be *much* smaller, because all the SCSI CD-Rs released in the
last few years have been MMC.

Yup. Since it's native OS isn't FreeBSD, it wouldn't vanish even if we
*did* put all of cdrecord in the kernel. I don't even see the port
vanishing, because of the need to support legacy hardware.

Correct. I'm not asking why cdrecord's functionality isn't in the
kernel, and wouldn't argue that it should be.  I'm asking why there
isn't support for a widely deployed standard interface to this
functionality when there's already a kernel API for it.

If it's a matter of not wanting to maintain that little bit of code,
I'm willing to do that.
