In the past we removed the jobs (ocata didn't have trusty jobs, IIRC),
and made sure backports were still passing the gates of newton with
trusty jobs voting. It may force a re-implementation in lower branches,
but it is fine for me, as ansible versions also differ and might
require re-implementation anyway.

That said, we didn't have the flexibility we have now with Zuul v3, and
making the jobs voting/nv/experimental.

The middle ground would be to have a non-voting check job.
It is fine, but it consumes resources for patches that aren't supposed
to be backported, and therefore I think it's not the greatest solution.

I like the "check experimental" part. It has an inconvenient: it relies
on our good behaviour:
When a bug is raised (so first element, we should not forget the bug
link!) for backport, we should all keep in mind to check experimental
before attempting the merge on the higher branch.

That said, I still prefer the "check experimental" that nothing.
You have my vote!
