> There's a faulty logic in {{Assign.usePolicyFramework()}} that makes the default policy (added in SOLR-12845) ineffective - that is, in the absence of any user-provided modifications to the policy rules the code reverts to LEGACY assignment.
> The logic in this method is convoluted and opaque, it's difficult for users to be sure what strategy is used when - instead we should make this choice explicit.
> (BTW, the default ruleset is probably too expensive for large clusters anyway, given the unresolved performance problems in the policy engine).
