To what extend to JVB and Jicofo follow the protocols as described in
https://xmpp.org/extensions/xep-0298.html ? Also, is there a XEP that
defines the usage of namespace http://jitsi.org/protocol/focus ?
We're considering replacing Jicofo with something that integrates with the
MUC (and later MIX) impelementation - no longer needing an explicity third
entity. However, we'd like to remain compatible with jitsi-meet. if it
turns out that jitsi-meet is based on behavior that's wildly different from
what's documented in the XEPs, the entire exercise will likely be futile.
