Google preferring JSON LD

"
I will try to get some more detailed statistics published from Google, but
as a first approximation I think I can reasonably share that we are seeing
JSON-LD on several million sites. Prior to
https://googlewebmastercentral.blogspot.co.uk/2014/09/improved-sitelinks-search-box.html
it was relatively obscure, except for use in email e.g. see
https://developers.google.com/schemas/formats/json-ld . Since JSON-LD only
became a W3C Recommendation in January 2014 this is pretty healthy adoption.

I should also mention that while JSON-LD is increasingly favoured as a
preferred syntax (over microdata/rdfa) for many Google features/products,
there are some for which Microdata continues to be the preferred format.
Since schema.org is defined in a syntax-neutral manner this is a relatively
minor complication.

I would like to offer this as new information Tanek's comment "JSON LD is a
non starter"

IMHO, this is strong evidence that this group should be standarizing around
this W3C REC, and push alternatives further towards a note.

Thoughts?
