1. there is no good name for this feature: "automatic" doesn't capture specific behaviour;
2. I don't understand why this specific use case needs any special support; and,
3. what advantage is expected from Mir being involved?
As discussed above:
Clients can implement this behaviour right now.
Toolkits can implement this behaviour right now.
Involving Mir would be to give the Window Management Policy another customization point should it choose not to allow the state request made by the client. But why is that useful?
