Centralized Sampling rules are not removed when they are deleted

I found this during my test, deleted a rule in the control panel but it was not refreshed in the app even after several "Polling sampling rules."
I did a bit of investigation and I think that when the RulePoller does retrieve the list of rules they are passed to the CentralizedManifest and there, only changes in priority or new rules trigger a full invalidation, otherwise, rules are updated but never deleted (even when the comment seems to indicate the contrary).
