No, release branches long pre-date freebsd-update.  However, before we 
switched to svn for source, new branches did not bump all the $FreeBSD$ tags.  
That is a side effect of the way that the SVN -> CVS exporter works (and 
arguably a bug).

BTW, I did design etcupdate to support this sort of use case (you can build a
tarball from a given release tree and use that as the basis for comparisons
assuming you were bootstrapped to use etcupdate).  Currently freebsd-update
doesn't use etcupdate and the author doesn't have any interest in changing it
to do so.

At some point if I have some time to hack on freebsd-update to be more useful
for modified versions of FreeBSD (e.g. building snaps from tags in an SVN
repository instead of a directory of patches against a CVS checkout), I will
probably hack it to support using etcupdate to manage /etc updates as well.

(etcupdate uses something akin to 'svn up' to update files in /etc, so things
like $FreeBSD$ changes just auto-update assuming they don't result in merge
conficts.)
