I think this requires an RFC. The behavior of
`MyController::myAction(...)` should align with
`Closure::fromCallable('MyController::myAction')`, and the latter is
forbidden today. We should use an RFC to support the behavior in both
places. We shouldn't try to sneak it in, especially as Nikita is
opposed.
