Thanks.

I'm the maintainer of openmpi, and used it as a testbed -- the first
path is the original (expected by many rdeps),
the second is the preferred, but depends on a patch not yet in gfortran
upstream.

Yes. The draft Fortran policy / recommendations that I'm writing include
explicitly that, and I'll be submitting patches
to move mod files from $include to $libdir/fortran/gfortran-mod-15
(Fortran does not change its modversion regularly so I'm reluctant to
put them in the gcc subdir, which is version-dependent)
