(I wasn't considering this initially since Conch is a generic SSH transport, and piggybacking on top of an existing OpenSSH socket is a highly-specific thing.)

Not only was this feature previously in Conch (although I'm not sure if it actually spoke OpenSSH's ControlMaster protocol or something custom?), but there's existing precedent for integrating with OpenSSH-based client-side tooling: Conch can talk to OpenSSH's agent via the agent protocol.
