Well we have JSON and agreed it was a good idea to have it. Now JSON is
a subset of YAML and some would prefer another YAML style (me included).

If the problem is supporting 2 formats in core rather than 3, what about
replacing the current JSON support with the YAML one?

At a later point we could even have JSON support back by having the YAML
printer able to output different YAML styles, but I guess that's not
where we are now.

Vote: +1 for YAML even if that means dropping JSON.
