> Note that the auto-submit test is only on creating a new page (in VisualEditor), so it's not a situation where reviewing changes is very meaningful - the entire page is 'new'.

Good point. Although it still doesn't eliminate the problem that one can't add a summary before the page is automatically saved. If someone creates a new page with the intention of adding more later, a summary may explain that. But if someone just creates a very short page with no explanation, an admin / moderator may simply remove it as spam before they can get a chance to improve it the following day or whenever. You're also discounting things like accidental mouse clicks, which can currently easily be cancelled but won't be in the future.

Perhaps if normal users could revert their page creations within say 15 minutes or so, that would make sense.
