UIScene migration is not yet enforced by Apple so we have some more time to handle this. Let's pause on auto-migrating projects.

Discussed with @vashworth that this is a just temp pause.

I think if we have to revert it, we may have to do a reverse migration for those already migrated.

Can you explain why we are pausing the migration? I think the status quo isn't actually a good place to stay either. We have already seen crashes in the wild where users attempt to adopt UISceneDelegates on their own (since Apple makes it pretty clear that's what it wants) and we haven't provided them with the mechanism to do it correctly which can lead to crashes: #168228

@hellohuanlin unfortunately we can't reverse migration because we can't distinguish between edits flutter tool has made and edits the users have made to the plist. You'd have to send out an email with instructions I think.

Notes from chat with @jmagman (cc @vashworth):

If we plan on leaving this paused we should add an integration test that runs with the project migrated to use UISceneDelegates. A lot of the testing story for the UISceneDelegate adoption assumed wide testing with the existing flutter test suite. We won't have that if it is paused in this way and we don't want it to atrophy while paused.
