I'm not convinced. There was nothing in that discussion why any
particular character would have to be allowed in a version number. I'd
propose that dashes should be prohibited in version names anyway,
because downstream packaging will want to use that to separate packaging
revisions. It might be better to discuss that explicitly rather than
hiding it in some thread of another title.
