Comment (by MarcusCalhoun-Lopez):

 Replying to [comment:1 dstrubbe]:
 > Could you explain in what sense you think this treatment is superior to
 the compiler portgroup? It seems like it is simpler by eliminating much of
 the functionality.
 Forgive me for not being clear on this point.[[BR]]
 I believe the compiler PortGroup could be simplified with the proposed
 changes.[[BR]]
 It could also be eliminated from any ports that **just** need Fortran and
 not the full power of the compilers PortGroup.

 The compiler PortGroup essentially bypasses portconfigure.tcl (see
 [https://github.com/macports/macports-
 ports/blob/5b53e2a643adef3de86eea608a746371984da310/_resources/port1.0/group/compilers-1.0.tcl#L299
 here] and [https://github.com/macports/macports-
 ports/blob/5b53e2a643adef3de86eea608a746371984da310/_resources/port1.0/group/compilers-1.0.tcl#L322
 here]).[[BR]]
 If portconfigure.tcl were updated, perhaps the code duplication could be
 eliminated.

 With G95 not having been updated [http://www.g95.org/g95_status.shtml in
 quite some time] and [https://github.com/flang-compiler/flang Flang] still
 being in early stages, [https://gcc.gnu.org/fortran/ GFortran] seems like
 the only feasible Fortran compiler for the time being.[[BR]]
 So for ports that just want a Fortran compiler, adding
 {{{compiler.require_fortran  yes}}} instead of using the compiler
 PortGroup seems reasonable.

 For those ports that still desire the ability to modify the compiler with
 variants, the compiler PortGroup would remain with full functionality but
 with a little less code.
