Btw. we might want to keep this open while the implementation MR is still in flight in case we end up deciding to make changes.

Sorry for the slow reply. On reflection I think I'd prefer two tweaks:

1. s/enable/supported/
2. put supported in the reply capabilities as well as the fd/fd index

My thinking here is that it's then much more like a negotiation of capabilities:

1. client: I support twin socket, please enable it if you do too
2. server: so do I, and here's the fd you should use

thoughts?

Works for me. And I'm assuming clients will bail and close the connection on inconsistent replies (such as supported being true, but fd_index absent).
