Comment (by birgire):

 [attachment:44314.2.diff] takes the same approach as #44341, using the
 [https://developer.wordpress.org/reference/functions/apply_filters_deprecated/
 apply_filters_deprecated()], available since 4.6:

 >When a filter hook is deprecated, the {{{apply_filters()}}} call is
 replaced with
 >{{{apply_filters_deprecated()}}}, which triggers a deprecation notice and
 then fires the
 >original filter hook.

 @desrosj and @garrett-eclipse, what's your take on this approach here?
