File's libmagic will always misdetect some files.
I'd like to see rpmbuild to prefer user.mime_type extended attribute over
libmagic guess. That way packagers could override the MIME type directly from
a spec file:
%install
setfattr -n 'user.mime_type' -v 'text/x-perl' %{buildroot}%{_bindir}/GET
If rpmbuild carried that attribute to RPM archive, rpm would set the attribute
when installing that package and it would become available to other tools like
fapolicyd-cli.
Technically we could patch libmagic to do that, but I feel that libmagic
upstream wouldn't like that. Maybe a place for an intermediate wrapper.
