I agree, but it is just one example. other test-only issues can happen as well.

Similar problem: the *client packages are not self-contained, they
have pretty strict dependencies on other packages. One case I already
run into was a dependency on python-requests: newer python-*client
packages (rightfully) require requests >= 1.x. running those on a
system that has OpenStack services from Grizzly or Folsom installed
cause a conflict: there are one or two that require requests to be <
1.0.

When you run gating on this scenario, I think the same flipping would
happen on e.g. requests as well, due to *client or the module being
installed in varying order.
