We currently have a large number of launchpad project, and even a larger number of git trees that come through gerrit. Some inbound issues aren't always clear which project the final fix is going to come in, especially if we are talking about a devstack, tempest, or docs change.
The current script that posts gerrit reviews into launchpad bugs does a very strict check that that gerrit tree matches the launchpad project, otherwise it won't post. So if a tempest change actually addresses a nova issue, the change won't be posted unless the person was disciplined enough to add tempest as a related project before the push.
In practice that's not happening enough that we are loosing valuable history in our launchpad bugs about related changes happening to address the issue in related projects.
It would be really good if instead of restricting the filter to just the exact launchpad project that matches gerrit, we allow posting to any launchpad that is an openstack project. Then the project could be added as related after gerrit reviews are out there, without any loss of history.
