for a discussion about making public builds (visible in milo to anyone) public in BQ too

That sounds really complicated. Is there a premade report one can use? Or are there plans to build something like the old thing? It was very handy to have an easily accessible breakdown of time spent and historical graphs.

It also sounds like something where all projects would have quite similar needs for the basic case. Asking every project to build it anew is a rather inefficient use of time. Having the data source available for more complex reports is cool, but smaller projects have much less time to deal with that and much less complex needs.

Today, we have no plans to add this feature to LUCI UI (Milo). It was a cool (stip@-made?) thing in our buildbot, but it wasn't sufficient for analysis in Chromium and afaik not that impactful for smaller projects.

does the line graph render for you?
