Well to be completely honest, a forum setup like XDA is terrible for development. It's impossible to keep track of anything.
You need a proper bug tracker for good development.
What's stopping you from using any of the good bug trackers? XDA's a forum, a place to discuss and share. If a particular development requires bug trackers the dev can create one and post a link. Same goes for code versioning.
