I believe this is correct. Anecdotally, at FB, there was quite a push to get coroutine-supporting-features into the standard because we had a C++ coroutine library built through non-standard means, which meant that compilers didn't fully support them (leading to a bunch of annoying things for all of those writing code on top of the library).

Now the folly/experimental/coro library can be compiled by anything that claims to support C++20, which is a pretty big win for FB if nothing else.
