RDA requires the data *only* when it is needed for one of those purposes, and allows the cataloger (or cataloging agency) to decide where to record the data (either as a separate element, or in the access point, or both). If there are negative consequences based on the decision of a cataloging agency to apply an "encylopedia creation" policy, those consequences are fully the responsibility of that cataloging agency; the developers of RDA have no part in that at all.

Every single element in RDA arises from a genuine "real life" need for such data in some context. That doesn't mean *all* contexts must also include the data. RDA defines elements so they're available when we need them. If we end up shooting ourselves in the foot by supplying them more than we need to, that's our own fault, not RDA's. RDA is very conservative in regard to core elements!
In defense of those who opt for more data instead of less, the point isn't "encyclopedia creation"; it's supplying data that--as time goes by--helps to further identify and differentiate the entity and to enable/refine automated data linkages.
