Comment (by pbiron):

 One downside of the approach in [attachment:"57999.1.diff"] and
 [attachment:"57999.diff"] is the can result in
 `get_{theme|plugin}_updates()` being called twice on the same page load of
 `update-core.php` (this was pointed out to me by @costdev.

 I've looked for a way to prevent those multiple calls, but as far as I can
 tell, that would take a major refactoring of the flow in `update-core.php`
 and I don't think that's worth it.  If someone else thinks they know an
 easy to do so, then I'm all ears.
