 While working on a pull request to prevent an undefined index notice in
 WP_Locale::get_weekday(), it became clear that the current behavior for
 invalid weekday values (e.g. 7) is intentional and covered by existing
 unit tests.

 This ticket is to discuss whether the current behavior should remain as-
 is, or whether a more explicit developer-facing warning (such as using
 _doing_it_wrong()) would be more appropriate, particularly for newer PHP
 versions.
