I think the OpenBSD and NetBSD lines are different in a third way as well: They represent the state of the upstream when we take it in, and from a 'keep deltas with upstream smaller rather than larger' perspective, it's good to retain them as well, even if we've substantially modified things since the import.... That was my initial thinking in keeping them. The reset of that thought is that the other remaining SVN / CVS / RCS / SCCS tags are from projects that no longer really have an upstream. They are defunkt now for many years (decades in all cases I'm familiar with, but I've not done a full audit to say that with certainty). They also date from a time where marking of sources and binaries was fundamentally different, and did things that we no longer do and are out of step. So there's no benefit to retaining it and some desire, at least to modernize.
