How hard would it be to extend the parser to handle arbitrary-precision numbers? Strictly speaking the JSON spec does not require numbers to fit into 64-bit ints / doubles.
Daniel Lemire did most of the work on the number handling, but our general approach was to try to do work that's similar to what the bulk of other libraries do. I believe pretty much everyone throws oversize numbers on the floor.
I don't think it would be hard at all; it would just be extra effort that wasn't needed to run obvious comparisons.
