What about using

every time?

Is there a drawback which we would like to avoid?

The DS website mentions two possible risks
- possible loss of changes on deleted replica should these have not been reflected to some other replicas
this is a theoretical concern that there might be changes from the replica to be removed which are not yet on all servers, but to me the problem that cleaning ruvs hangs because replicas cannot be reached is the worse scenario.
- if some offline replica comes back online, it may re-pollute the RUVs back

I'm not sure of the probability of the second scenario, in my rather simple environment the re-pollution did not happen.
there have been fixes in 389-ds to prevent the repollution, so it should no longer happen.
