Forum channels bridging

Is your feature request related to a problem? Please describe. Discord unveiled forum channels, which are channels that cannot have any top level messages posted, instead, they can only posted messages within a thread.

Describe the solution you’d like Forum channels should be bridges as spaces, and threads within it as chat rooms with knock_restricted join rule. Auto-archival by Discord should not be bridged, however, manual archival should be bridged.

Describe alternatives you’ve considered Threads-as-relations, but not useful in this use case

I feel like the best way is to create matrix threads in a room, and have the app auto create the threads matrix<->discord.

1 forum thread on discord <-> 1 thread in a room on matrix

Each message in matrix channel creates a thread on discord, and the thread is started on the matrix side with a message of “this conversation is now a thread” and alerts the user to the thread.

This preserves history of threads, and keeps it organized.

the only complication I see is deciding what to treat as the thread title and what to treat as the message body from the matrix side

First line is title, the rest is body
