Yes, I've seen this, and I loved it.

Mostly is is just a nice fast link right to the test case failure or build failure.

Me too, but latent *code* problems introduced before this build need
to show up somewhere, and it's non-trivial to detect those kind of
errors based on the blame list alone. An example of this is the C++
They're rare enough that we can deal with them. But they look *a lot*
like flaky bots, enough that could trigger people to disable bots
without further consideration.

Excellent! I have some spare hardware that I can use for experimental builders.
But, this being Jenkins, I suspect you'll need to push the jobs
through, rather than me pulling them like buildbots. For that, I'll
need some firewall configurations.
Just let me know when you're ready! :)
