Sure, that's fine, we just all need to decide on something.

Yep, agreed.

This is one of my goals. Having this logic in one place would cut down
on a lot of code duplication and unexpected behavior.

That would be a great benefit of everything using one port group for
this: easily changing the default gfortran for all ports.
