Yes sorry
Yes, that’s a great idea. Many Whonix users are new to linux. It would be more convenient for them to install and learn about recommended or reviewed messengers on a separate page. They might get confused on a wiki/Chat page, and accidentally click a command for a different messenger. The wiki/Chat page could contain a general overview and brief notes for unsupported messengers - for example, for Briar you could simply add: “Tor over Tor issue not resolved. Check this: Briar Desktop in Whonix”
For XMPP and Matrix clients, you can add separate “XMPP” and “Matrix” pages and publish reviews of all clients. XMPP and Matrix have too many clients to create a separate page for each one.
