Hello Charles,
Is there a way for a server to yield back resources to its clients symmetrically to the upgrading protocol, ideally that doesn't require modifying the parent interface?
there is currently no inverse operation of a session upgrade. A client has to close a session to regain the resources.
I'd be interested to learn more about your particular use case as the parent and root interfaces will undergo a revision soon (turning blocking RPC calls into asynchronous interactions). So I wonder if your use case may contribute to the new design?
Cheers Norman
