I don't think we're on a track to make IContainerContext internal, but rather I think an equivalent eventually may become part of the public API. This is (currently) required for the extensibility point of a customer-defined IRuntimeFactory, which is actually a useful tool. The interfaces could do with a lot of improvements, but the core concept seems valuable.

Interesting crossroads. ISignalEnvelope is internal and the required type to pass to submitSignalFn.
I guess the TODO is to remove submitSignalFn from this interface and offer an alternative if needed. Maybe Presence notifications would be sufficient.
