Generally speaking, making sure it works fine outside the gate is in
my opinion an interesting information, as we know developers tend to
take care of devstack only (and I understand why).
But yes, things like:
- making sure a change is backward compatible outside devstack
(configuration or behaviors): using TripleO job now, but why not Kolla
or another tool in the Big Tent?
- test real upgrades, looking at sdake's reply it seems like Kolla has
a bunch of jobs for that.

Also I proposed to use the experimental pipeline right now because I
like to iterate. If we see some benefits and results, I would be in
favor of moving the jobs to the check pipeline, as non-voting.

Thanks Matt for being open of such a change,
Emilien Macchi
