Peter didn't say "on the web" or "on the net."  He said "for public data
interchange among general users."  There's a difference; although it may
seem hard to believe sometimes, there is still data that is publicly
interchanged in forms other than Web pages.  BCP 47 tags are meant to be
useful for any such data.

I do agree with Peter, and probably with CE, that subtags should be
registered for the purpose of tagging real data that is publicly
interchanged, and not just to provide a historical record.
