As I understood it. Your proposal was to change the lookup strategy for
port groups, which is currently tied to the lookup for all files in

I only wanted to sketch a scenario where overriding files in _resources
does not apply and a new lookup strategy might not work. I was not only
thinking of port groups.

Maybe. The point of _resources/port1.0/ is to keep them separate for
each PortSystem. Whether this versioning is necessary is arguable.

The other option would be to properly document how the lookup works for
the files in _resources.

At the beginning of this thread I linked where the PortGroup lookup
happens. So if you have a plan and can work it out, I'll gladly review
any patches.
