It takes time to weave new specifications such as LDP into the existing fabric of specifications. The fact that it may take a few years for this sentence to appear is no excuse for harming compatibility now, in my eyes.

5. keep text/turtle - there is no problem.

We do it because we adopt an RDF based Linked Data community best practice, not because of any semantics in the media type specification for text/turtle or any other media type associated with RDF.
