I'd prefer to keep some gating jobs (non-OVB) that deploy pacemaker,
so that we have coverage of pacemaker in the gate.  I'm not sure if
that's what your followup comment about standalone was implying. If it
was then the plan sounds ok to me, otherwise I'd be concerned about
the loss of pacemaker coverage.
