 +perl5_22` with an upgrade until we actually remove the `perl5_16` variant
 (but they will have to rebuild the port for no benefit)

 An upgrade will rebuild the variant they currently have if available.  An
 install will get the new variant.  This assumes that
 perl5 is not installed with a different variant.  If it is, then the port
 group will take perl5's variant as the default.  If perl5
 is not installed the port group now falls back to 5.22 (the buildbot
 case).

 the buildbots?

 Perhaps, but I'm not worried about conservation of revision numbers and I
 wanted to make the point that something new is going on.
