Not talking about DSON, it is more of a translation format than one used for creating figures and such.  I could be wrong, but does anyone create natively used content in the DSON format?

 I am just pretending I am a company and looking to change what I am doing.  What would make the best sense for me, the company, and my users?  Everything seems to boil down to having a program that can create, edit, and work with content written in a format that is flexible, robust, stable, open, and supporting all the features needed by the users to do the things they want.  In general, that is usually the industry standard format, even if it is not given an official seal of approval by the industry.  The company that develops that format is going to be the one that wins out.
