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.
