This doesn't really make sense to me. Just because JSON is human-readable doesn't mean that humans are meant to read any possible serialized data nor that it should always be an ergonomic read. Not everything you serialize is just a config file or hand-edited data. It may be arbitrarily dense with arbitrary data.

To me, this is kinda like seeing a JSON array of user IDs coming over the network and going "Huh? Why not usernames? I thought JSON was supposed to be human-readable!"
