Comment:

 WP 6.9 deleted `wp-includes/SimplePie/src/Core.php`.
 Upgrading to WP 6.9 did not remove the file on the two installs I tested.

 The deletion was in the upgrade to SimpolePie 1.8.1:
 https://core.trac.wordpress.org/changeset/60490
 https://core.trac.wordpress.org/ticket/63717

 Then it was upgraded to 1.9 before the WP 6.9 release.

 As far as I can tell, 1.8.1 was not in a WP release. (You may want to
 search "simple pie" as well as "simplepie" in the various trac places.)

 Is the lack of deletion on upgrade a bug?
