When I started implementing support for limiting the list of returned identifiers in PHP, mostly for UI reasons, I found that I could restrict on region. A region f.e. being "America/" or "Europe/" or "Pacific/". Because that list is still way too big for people to choose from, I further restricted that on country code because the tz project conveniently provided that.
FreeBSD's tzsetup(8) utility does the same thing for pretty much the same reason. -GAWollman
