A project that I work on has a (formal) requirement that use-clauses must restrict imported symbols via "only". (However, many contributors simply ignore that rule, since the compiler used does not complain.) g95 provides -Wunused-module-procs and -Wunused-module-vars to provide this diagnostics which is what I use for "cleaning up". I do not consider this useless diagnostics. Obviously, this only works as long as the code is still compilable by g95 ...
