True, folks are very familiar with JSON, but it does have problems, and the best time to pick the best solution is before one has to deprecate a lesser solution. Computing is built atop a pile of decisions which made sense at the time and cannot be changed now due to compatibility (spaces in Makefiles, anyone?): there is no time like the present to simply choose to do the most correct thing. 'But folks won't use it!' Well, they might not. But if one gives folks a choice between the capability they need using an unfamiliar technology and not having the capability at all, they will learn the unfamiliar tech.
