I think we should try to improve Microdata. It has proven to be a useful syntax for data markup in HTML. The move towards JSON-LD for more granular data in HTML will happen, IMO, in parallel and in other areas - like pages with a lot of data (e.g. automotive data sheets), quickly changing data (e.g. airfare tickets or timetable information), and in general RESTful APIs.

I think the new @itemrole keyword with "rel" and "rev" as supported values and "rel" being the default is best. It is conceptually cleaner (since rel vs. rel is a modifier of the itemprop keyword) and it is backwards-compatible (no existing markup has to be changed).
