Comment (by westonruter):

 And #38072 is about removing the use of such negative IDs as placeholders.

 Nevertheless, the `get_{$meta_type}_metadata` filter is actually like
 `pre` filters elsewhere, as it short-circuits the filter returns a value.
 It is similar to `pre_option_{$option}` in this regard.
