Fair enough. Someone else had just commented that programmatic
submission was hard, or complex, and made worse by the patch.

Well... Yes. That was what the patch did. It changed the system to use
form processing hooks for CRUD interaction. It can definitely be said
that there should be an easier way to 'tie in' to those operations. A
specific helper function rather than form_alter, for example.
