That could also be a selector, right?

The problem with a request header is caching: requests to the same URL
might get different results based on that header, so I think you also
need a Vary: header to be clean w.r.t. caching. Not impossible but
easy to overlook.

A selector doesn't have that problem - but if it's a selector we'd
need to reserve a selector namespace for sling, which is not too
convenient either.

No strong opinion at this point, just thoughts.
