you know I asked for this in the JP side also in the past but no response.
The forum base is vbulletin and looking at the rss feed it generates it's using type=rss2 so did a search on available parameters for rss2 and only thing available is the forumid= which only can be specified to specific forum (being general discussion, UI, or w/e, not actual thread itself)

Also noticed the searchid on the dev tracker page always changes (increases) so everytime a new request is sent it needs to add new searchid to spit out the new info so you can't stick a rss tool to see what changes were made on that dev tracker manually either.

If it was possible to create a forum (section) that sticks all the rep/dev responses then we should be able to get RSS...

At least I got that far, but gave up after lol.
