Sorry, missed part of the sentence.
There are several ways how one can implement it. I would personally
prefer pull requests to dist-git over scratch builds. I think it is
important to keep some visibility in the system, so that not just the
owner of a change, but also random lurkers can see what is being
prepared.
(Also solves the issue )
Please read as: Also solves the issue when there are overlapping
sidetags prepared by different people.
One can subscribe to pull-requests in a project, and get early alerts
about planned changes.
