TaskGroup: Keeping a Reference to Child Tasks?

Here's a recent thread on this: @_inheritActorContext does not inherit the actor context in certain situations You can confirm the behavior yourself based on those snippets.

As usual with concurrency and guarantees it is not quite as naive and trivial to declare it'll be simple...

Do we guarantee that they're finished or finished and DESTROYED? Because that's what we actually do today.

It's worth an in depth investigation, but it's not as simple as just a missing method we can just throw on there. It might have big implications.
