Users of coroutine-friendly libraries will have to adopt the async function coloring (co_await, co_yield, co_return, Task<T>). So saying that coroutines are l

  Not necessarily. Coroutines are invisible at the ABI level (that is coroutines are just functions). It's pretty easy to write a library with them (using your own executor) and not reveal their use to the user. Obviously sharing an executor between application and library is another matter.

    Good point. Although doesn't that defeat the purpose of structured concurrency? i.e. creating tasks that are plumbed to some background thread/executor. By directly invoking the coroutine, lifetime issues become much easier to avoid.
