I'd be happy enough to see greater granularity for rdfs:seeAlso. I have a use case where I want to say something like "the <uri> has been minted recently by a source that is not authoritative but that, if widely adopted, could become so. Either way, it's worth noting that he and I are talking about the same thing" - and rdfs:seeAlso doesn't really cover that nuance! However... a property should not imply any content type AFAIAC. That's the job of the HTTP Headers. If software de-references an rdfs:seeAlso object and only expects RDF then it should have a suitable accept header. if the server can't respond with that content type, there are codes to handle that.
