We would still like to have support for gfortran family of options, but I think that could be added as a thin wiring in the driver to your option (as in a user defined `-finit-local-zero` wires internally to your option). Of course, that could come as a separate set of PRs (we will also contribute on that).

Thank you very much @NimishMishra for confirming!
PR #216164 should already have `-finit-local-zero` available to users with the underline implementation as an aliasing to `-finit-local=zero`. We can definitely look into it as a separate PR if it needs more tuning and adjustment.
