In my opinion this is much easier to reason about because you never have to think "some async functions care about where they're called from and others don't", it's just "async functions never care about their caller".

Which isn't true anymore because of isolated parameters with #isolation. I think this bugs everyone at first, and for good reasons. For example, non-sendable types are isolated to the domain where they are used but their async functions will hop to a different isolation. This is really strange behavior I think.
