Author of Wardgate here:

Definitely something that can be looked into.

Wardgate is (deliberately) not part of the agent. This means separation, which is good and bad. In this case it would perhaps be hard to track, in a secure way, agent sessions. You would need to trust the agent to not cache sessions for cross use. Far sought right now, but agents get quiet creative already to solve their problem within the capabilities of their sandbox.
