@niftylettuce I suppose this is ready for review. I'm not crazy about the implementation. There is definitely some overlap between the use of exports.js and the renamed isBinary() function. That was already the case, and I had a bit of a hard time determining which was the best way to solve this issue. Some refactoring of these two bits might make it easier to provide the ability for developers to declare the desired behavior - or at least consolidate some of the data format guessing game. But that's a bigger change than I am willing to get into. The fix provided in this PR really only addresses my personal use case and perhaps a couple of others.
