True.  However, if a fix is needed and checked in, in order to retag,
it's hard to tag the new svn head but exclude the unnecessary change.
Around release time, it really is useful to have a separate branch to
handle the release.  In the case of an unstable build, the release
engineer can merge all of trunk to the unstable release branch and tag
from it.  Changes can continue to go into trunk.  Changes needed to
create the unstable release can go on the unstable release branch and be
merged back to trunk.
