It ok, I guess oVirt Jira is not anyone's favorite reading material ;)

Yep that is where we want to be.

Its not something that Zuul allows you to heavily customize - and I am
hoping we will manage to get more efficient with the builds. Besides -
looking at a common scenario now - where the maintainer merges a set
of patches before leaving the office for the night, having the CI
system crunch all night and bring results in the morning is not such a
bad thing. Way better then finding out which patch broke the
experimental flow 3 days later.

Hopefully we get to the point where they are rare.

Just to make things clear - Zuul does not do any magic with Gerrit's
"submit" button - one needs to use a flag instead.
