has_filter() returns priority, which means it can return 0. But core doesn't check for it being identical to false. We should audit all has_filter() calls and make sure 'false !==' or 'false ===' depending on what we want.
Additionally remove_filter() has an $accepted_args argument, but doesn't use it. We should eliminate it from the function definition and docs.
