Alright. That makes sense and is also mirrored somewhat by the Advisory Board feedback (see my last mail to Wei). What is your view on the usefulness of keeping Preview and Experimental separate? It sounds to me that we should fold these into one category and let Limitations, Improvements and Known Issues speak for themselves.
