That would be a *LOT* of extra work!  Who would do it?  You really
really do not want to introduce unnecessary branches in CVS, especially
not on entire modules as large as a whole multi-platform operating
system!  ;-)

I think the NetBSD scheme of branching is more or less sufficient.  As
others have already said, the stability of NetBSD branches is much
higher than that of any FreeBSD -STABLE branch, and indeed the concept
is much more along the lines of the FreeBSD RELENG_* branches.

That said I have seen reports of errors cropping up on the NetBSD
release branches.  The solution though isn't more branching -- it's just
more patience on the part of the most paranoid of users.  What they need
to do is:

	$ cd /work/netbsd-1.5-branch
	$ cvs update
	$ sleep 172800
	$ make dependall	# if it breaks, go to step #1 again
	$ sleep 172800
	$ make install

While sleeping, in both phases, keep a very close eye on the various
NetBSD lists for any reports by less paranoid users about any issues
that might have cropped up.  :-)
