 Perhaps in `WP_Hook::build_preinitialized_hooks()` as it exists to fix
 that "bad behavior".

 Marking it with deprecation for cache drop-ins would be a good idea, IMO.
 I don't think it should trigger that for hooks declared before WP is
 loaded though, since there's no alternative to setting `$wp_filter` if WP
 hasn't yet loaded.
