This strikes me as a quality of implementation expectation, not an interoperability mandate, so maybe wording with “clients are encouraged” is actually appropriate.

We've used SHOULD to encourage behaviour with good network effects / social benefit before -- e.g., sending caching metadata. Personally, I think this falls in the same bucket; the client's behaviour here has strong impact on the network and server (indeed, the network impact is one of the major reasons we're doing /2).
