Comment (by westonruter):

 In [changeset:"62408" 62408]:
 {{{
 #!CommitTicketReference repository="" revision="62408"
 Plugins: Improve hook performance by using `spl_object_id()` instead of
 `spl_object_hash()` to construct unique IDs.

 * Also use `spl_object_id()` similarly when registering and unregistering
 classic widgets.
 * Improve typing and phpdoc in `_wp_filter_build_unique_id()`. Return
 `null` for malformed callbacks.
 * Add tests for `_wp_filter_build_unique_id()`.
 * Improve type safety of `WP_Hook::add_filter()` in case an invalid
 callback is provided for parity with `::has_filter()` and
 `::remove_filter()`.

 Developed in https://github.com/WordPress/wordpress-develop/pull/11865
 Follow-up to r46220, r46801, r60179.
