No, the tag contributes to the grouping; the policy is identified by the
choice of command line switch (--affinity vs. --anti-affinity).

membership is declared in a different way than in the current server
groups feature. Jay's proposal is not really about *removing* server
groups but rather it is a proposal to change their API.
