If your random 256-bit public key is accidentally the prefix or suffix
of something else somewhere else, you have a problem with your RNG.

Anyway, JSON is not regular, though it is context-free, which I think
is your argument. If I had to choose between the two, I'd easily
choose something that's regular to parse, since it can be implemented
in a bug free fashion trivially anywhere.
