Any reason to keep bibliography in YAML?

[Joseph Reagle <joseph.2011-T1oY19WcHSwdnm+yROfE0A@public.gmane.org>]

My biblio tool can now create JSON-CSL output -- in addition to bibtex, biblatex, YAML-CSL, and Wikipedia citation template.

The JSON functionality is rather redundant with YAML, which I'm inclined to delete.
pandoc is so much faster with JSON, and if JSON is YAML, I can't see much reason to keep YAML.
I can even embed JSON-CSL in markdown files, just like YAML-CSL, as seen in example below.

Before I gut the YAML functionality and tweak my build system for the CSL, is there any reason to keep it?
