Can we use a Document& and a Ref<WebXRSession>&&?

scriptExecutionContext() might be null.
s/ScriptExecutionContext&/auto&/

referenceSpace.releaseNonNull()

Why do we need this one?

We could indeed pass a Document&, I just used the ScriptExecutionContext* because that's what ContextDestructionObserver expects in the end but I can change it.

Regarding a ref to the session yeah we could do that as well as the session does not keep any reference to the reference spaces so there is no risk of ref cycles.

I don't see any reason.
