 It's not as nice as #14671's proposal, but it's better than nothing.
 Saying that, since WordPress 5.0 is round the corner, could this be the
 time to break backwards compatibility regarding `intval` as a filter? The
 message could just be: don't use `intval` and other functions that don't
 have a suitable signature for a WordPress sanitization filter.
