--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This is intentional, see https://wg21.link/lwg3460 which is expected to be
voted into the draft in a few weeks. The inheritance requires unimplementable
and nonsensical behaviour.
You can still do this:
std::coroutine_handle<task::promise_type> c;
std::coroutine_handle<> c2 = c;
You just can't bind a coroutine_handle<> reference to a coroutine_handle<P>
directly.
