On the overall topic here is a (related) idea I've had lying around: - Contact distribution maintainers to patch their glamor packages as far back as possible. Having a mesa-maintainers ML or alike might help, they are likely to miss this in mesa-dev, plus pinging individuals does not scale. - Decide on transition period, where we'll have a) the patch reverted or b) a glamor hack in place. - Transition period is over - patch is back in/hack is out. The communication medium can be used to get the maintainers attention to other topics that directly concern them. They could also voice their like/dislike towards X and Y. How does the above sound ?
