Fixing this sort of issue is almost certainly a bad idea.  This would
involve effort towards CVS.  CVS's last official update was a decade ago.
CVS is likely security swiss cheese at this point.  Better to convert to
anything else sooner than put effort towards CVS.

Which suggests getting rid of CVS is the greater concern over what is
moved to.  I'm pretty sure many people will snicker at NetBSD moving to
Mercurial, though plenty will be relieved it is off CVS.
