 It would be useful for themes/plugins/core to have a way to rename a hook
 with a another hook, such that when `add_filter($tag, $fn)` is called, the
 `$tag` is replaced with another tag. Syntactically, maybe:

 - `rename_filter($old_tag, $replacement_tag)`
 - `deprecate_filter($old_tag, $optional_replacement_tag)`

 Or `$tag` could be made filterable as `add_filter` is called. This would
 add a lot of capabilities:

 {{{
 if ( ! apply_filters('add_filter_args', func_get_args()))
     return false;
 }}}

 Or, still many capabilities, and safer:

 {{{
 if (false === apply_filters('hook_tag', $tag, $fn, $priority, $accept)
     return false;
 }}}

 Consider: #23259
