To be fair about it, the answer is 'no, you do not need CAm to support new
hardware'. It just makes it easier to port Justin's latest && greatest.
When I get finished porting my Qlogic target mode (which I've had working
under Solaris for a month or so) back into the common driver (common for
FreeBSD, NetBSD, Linux) there'll be a framework ready for it in
FreeBSD/CAM but not as much of a one in NetBSD.

Sure. There are incremental changes going on all the time in the current
SCSI layer. I even added a few even though I'm more interested in CAM
development at this time.
