Triage: Assign issues to groups/teams

It would be useful to be allow a kind of hierarchical triage on drupal.org, similar to launchpad.net.

Rationale:
There are about 50k open issues with 0 replies, and tens of thousands more with only one - many of which probably haven't been looked at by anyone who is familiar with drupal enough to properly answer the issue. Triage would potentially speed up the process of cutting down the work load on core maintainers, as users who are have an intermediate familiarity with drupal would be able to pass on the issue to groups who are certain to be able to answer the question. This is especially useful for issues for which the project, project component, and category are somewhat uncertain.

Use case:
- Newbie posts a bug, which has something to do with a particular topic, but is a bit confused.
- User with a "triage" permission (a la Docs Team) asks for clarification, and when satisfied, assigns the bug to the appropriate "team" - eg - UI, Core, performance, etc.
- All user in the appropriate team have the issue posted in their triage queue, and once then someone with some expertise looks at it, they can leave it assigned to the group, for more discussion, or assign it to a particular user to work on.

I'm not sure how the groups should be implemented, but I guess looking in to using OG would be the obvious first step. I also guess that OG might not be a popular addition to drupal.org without some better reasons, so perhaps there are other ways of implementing triage without using OG. Allowing users to subscribe to project categories might be a partial solution, but that's pretty useless when it's uncertain which project the issue applies to.
