AFAIK Linux has been GPLv2 only since version 2.4.0, i.e. from January 4th
2001.  Work on GPLv3 didn't start until late 2005.

Personally I think it's only prudent to know *exactly* what license SW I write
is released under.  So releasing under GPLv3 only before GPLv4 is released
makes sense; I also think that applying licenses retroactively is troublesome,
so it's worth being specific from the beginning.

OTOH it doesn't bother me at all that Arch's packaging system currently lacks
a way of accurately specifying the license for some software.  I think it's
very little chance of that ever counting for anything in court.  As long as
upstream provide clear information the Arch package can say pretty much
