May you please elaborate why exactly do we need to rewrite everything?
If we agree that async threads will have limitations, we may as well
start small, allowing a limited number of functions to be used. The
functions that do not support true async will then switch to the
cooperative mode, possibly throwing a warning.

Later, if it is truly necessary to rewrite things for async, it can be
done gradually.
