Thanks for the reviews over the last few rounds, this has shaped up quite well.

That specific capability "don't inherit" was something that came up in a few contexts and is definitely something we can do in the future.

With the property wrapper approach it may be a bit weird how to express this, we may need a new wrapper? Because the goal with `@TaskLocal` would be to cause compile time Sendable-check failures once we're ready to enable them across the board, so it'd be hard to not do that check for `@TaskLocal(inherit: .never)`, but it's something we could do in _some way_ for sure.
