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) > Grub and Libreoffice also ship .mod files.
