So we don't know how much each of those modifications contributed to the space difference.

Ports that used to depend simply on port:gccXY because they need either Java or Fortran will need to change to using a path: style dependency on a representative component; that should call for installation of the "uncut" port if that component is missing.

You can't have two ports install files to the same locations without conflicting with one another. And having two ports install the same files is redundant and counterproductive.
