I would go further and say that the beauty of the views provided in 0.8 is that there is so little to set up.

I hate to jump into the middle of the thread here, but I think that some of the discussion could use a bit of context.

Even if there is a version of Buildbot 0.8 with usage metrics support, a lot of corporate installations are not going to be able to report metrics. At that point, in order to compare the uptake of certain features in 0.8 and 0.9, you will need to rely on reports from users. And from experience on other open-source projects, users tend to report specifics like this only when they see a regression.

For my use case, I don't see the regression because we did not hit any of the limits in 0.8 that would cause the new architecture of 0.9 to be worth the upgrade. Rather than using multi-master setups, we divided things up and scaled horizontally, then aggregated the data from the various buildmasters. I'm not sure how we would begin to approach that in 0.9 - some of the developers even ran with JavaScript disabled by default in their browsers. Developers with Python experience are not always well-versed in JS.

I don't have the numbers to back this up, either, but I suspect that a lot of long-time Buildbot users have been able to deal with multi-project builds with triggers, and by presenting subsets of the builders in each status display.

If the move is towards just embedding status in Github/Gitlab pull requests, I wonder how Buildbot will differentiate itself from other projects like the CI pipelines in Gitlab.
