As I mentioned to Sehrope on IRC, at least for my 2c, if you want a
compact JSON format to reduce the amount of traffic over the wire or to
do things with on the client side, we should probably come up with a
binary format, rather than just hack out the whitespace.  It's not like
representing numbers using ASCII characters is terribly efficient
either.
