      Looks like it's possible to hint an index that has one collation defined but specify a different collation on the query itself.

      It should probably be an error, similar to requests in SERVER-8564 but I can also see this being a warning, since it's possible to conceive a query that is using default collation but wants to use an existing different collation index for filtering in a scenario where this does not impact the results.
