So it sounds like the state required to recover from a crashed compositor is a SUPERSET of that required to restore state after a fresh start.

So why not implement the state required to recover, and get a fresh start FOR FREE? If you have to do all that work anyway, why not take advantage of it?

No - they have very little in common (see my other comment for details). Your position is like saying that because motorbikes and planes can both get you from point A to point B, but a plane carries more people, a pilot's licence is clearly a superset of a motorbike licence.

Both have window positions. But that's all that they have in common; one has details of how to start applications and get them to create the windows you need them to create to restore state after a fresh start. The other has details of how to pretend to already-running applications that the compositor never crashed, and thus they don't have to create new windows at all.
