xmin is not yet advanced. In this state, we ensured that the
subscriber has caught up with the publisher and now the apply worker
can start maintaining/advancing its xmin.

Right, so will use your version.

We thought adding for one of these cases is sufficient to avoid
increasing the test timing further. These are time sensitive tests as
apply-worker on subscriber is dependent on actions of publisher, so we
need wait logic.  Otherwise, it seems doable to once again stop the
retention and resume due to a non-zero value of
max_retention_duration.
