Do you mean to *disallow* using yield-from for this, or just
not to encourage it?

I don't see how you *could* disallow it; there's no way for
the scheduler to know whether one of the generators it's
handling is delegating using yield-from.

I also can't see any reason you would want to discourage it.
Given that yield-from exists, it's an obvious thing to do.
