Re: YAML Was: CommitFest status/management

Can I ask the final decision whether the YAML formatter should be
applied or rejected?  As far as I read the discussion, we can apply it
because serveral users want it and we don't have a plan to support
extensible formatters in the core.

Comments from additional discussion:
 - YAML format is the second (or the best for some people)   human-unreadabe format for EXPLAIN output.
 - JSON is not always a subset of YAML. It is not recommended to   generate/parse YAML with a JSON generator/parser or
viceversa.
 
 - We won't add any core hooks and plug-in to format EXPLAIN output.   Client tools may convert the output if needed.
(ex.using XLST)
 
 - The spec of YAML might be changed in the feature, but we use   only the basic parts. The parts will not be changed.
