This clearly won't scale but it should be enough to pass conformance tests on platforms that might not have VM support for continuations for some time. Part of that needs to separate "supported by VM" from "preview features are enabled" as it has to be surfaced to the library code so it can choose the implementation.

That's excellent news. Thank you.
