Thank you for the suggestion! This seems to be a fork of mosh upstream that adds out-of-band "reliable byte streams" to the client-server protocol (based on Timo Rinne's patches from 2012-2013, https://github.com/mobile-shell/mosh/issues/120).
Mosh upstream (https://mosh.org) doesn't have this protocol addition; the developers aren't eager to complicate (and forever support) the protocol in this way. If people want to do agent forwarding, Mosh has mostly encouraged people to do it with a separate tool (guardian-agent was one of them that was more locked-down than normal SSH agent-forwarding, but it's also possible to use a separate SSH/autossh/et connection to carry the agent-forwarding byte stream).
