So I'll ping him on IRC but I'd like to see a path for making that test work in
the gate otherwise I think we should just pull it. Otherwise it'll never be run
with other proposed commits and will probably bitrot fairly quickly.

So the flag to make tenant isolation was always a temporary thing just for
neutron so we could work out stabilizing things. It's been on by default for
all the other jobs for as long as I can remember. If you think that we've
reached the point were we can greenlight it everywhere, I'll push out the infra
changes to do that.

Yeah, that makes sense, but I still think we should keep 4 tempest jobs running
for the neutron queue. Do you have any ideas for other configs or should we just
duplicate the existing 2? (postgres and mysql)
