Updated alternatiive to #38233 ...
Significant changes here. This focuses entirely on the internal API surface and does not expose any public API yet. That is intentional to allow us to work through this and was agreed on at the last collaborators summit.
The tests here are woefully incomplete and will be evolved over time.
It's a very big PR. If folks want help getting started on how to review I'm happy to walk through it. The prior PR bit rotted badly and had to be nearly completely redone.
Expect bugs. This will continue to be a work in progress for a bit.
