I propose we keep $select and $expand separate. $expand and $select are different parts of the query, handled and evaluated at different points in time (similar to FROM and SELECT clauses in SQL). $expand is evaluated before $select and identifies the full set of entities available to the client. Once that full set of data is defined, $select allows the client to select the properties of those entities that are of interest from that set of data. We are looking at extending $expand to include things like filtering and sorting of the related entities. I would not like to introduce complexity by saying that $expand is used in some case (i.e., where filtering/sorting of related entities is required) but not used in other cases.
