I don't think you'd need to have two versions.

If I have a sync function and I call something async, I should be able to just .wait() it, I think, and get the sync behavior.

Technically you do not, as you pointed out you can use the cps version for everything, but it is suboptimal, especially for interoperability with other languages and the os.
