This RFC essentially comes down to where Arch positions itself.  When
Arch was founded, it was explicitly built for modern CPUs and that was
stated as one of its distinguishing features.  Firstly i586, then bumped
to i686.

This RFC is asking whether we still follow this founding principle.


BTW, the tooling to do a -v2 and/or -v3 port is already there.  Nothing
much has changed in terms of tooling since we removed i686.  So adding a
port is simple.  What is an issue is whether we want a build server to
monitor the repos for differences and automatically fill them.  That
would require package signing infrastructure that we have not achieve
for databases in 9.5 years...
