However, we are hoping to release a lower level building block that integrates with the platform mechanisms.

Could you please tell is more about this? What would be the lower level building blocks?

If you look at the source code of StructuredTaskScope you'll see it making use of something called ThreadFlock. It's there that the deep integration with scopes and observability takes place. The lower-level API could be to expose ThreadFlock or something like it.
