Comment 2 for bug 411357

It'd be important for us to have it, since we'd like to create lists of all the source package branches that need reviewing to get them uploaded into Ubuntu. At the moment that'd be:

 * https://code.launchpad.net/~ubuntu-branches/+activereviews
 * https://code.launchpad.net/~ubuntu-main-sponsors/+activereviews
 * https://code.launchpad.net/~ubuntu-universe-sponsors/+activereviews

With Archive Reorganisation I expect there's going to be more quite soon.
