Yes, resources are always meant to be for the very ports tree they are
in. If the file is not provided by this ports tree, the default ports
tree will be used.

Does your custom ports tree not just provide a custom implementation of
this port group? Or do the ports using this modified port group not need
any further modifications, but you do not want to copy all Portfiles to
your ports tree?
The lookup strategy is also the same for mirror/archive sites, variant
descriptions, livecheck. I am not sure whether it would make sense to
change this for all of them (for example archive sites are definitely
only local to a ports tree) or to introduce a special lookup just for
