Arguably the Enterprise universe is a slightly less tangential one than the JJ one.

There was the OS universe which has multiple futures and there are many near alternates like the Mirror universe and the one where The Enterprise D continued long enough to grow an ugly third nacelle.

That would mean a many worlds approach to time travel resulting in The Whale Probe actually wiping out all life on Earth in their universe because TMP Kirk dropped George and Gracie into an alternate future.
