Public facing interfaces are their own special thing, regardless if json or anything else, and not all data is a public facing interface.

If you need it, then you need it. But if you don't need it, then you don't need it. There is a non-trivial value in the smallness and simplicity, and a non-trivial cost in trying to handle infinity problems when you don't have infinity use-case.

This is a serialization library. The entire point is to communicate with data that's coming from out of process. It should be safe by default especially if it's adding a quick check to avoid overflow and undefined behavior.

		Incorrect assumption. If you are reading data from a file or stream that only you yourself wrote some other time, then it's true that data could possibly have been corrupted or something, but it's not true that it's automatically worth worrying about enough to justify making the code and thus it's bug surface larger. How likely is the problem, how bad are the consequences if the problem happens, how many edge cases could possibly exist, how much code does it take to handle them all? None of these are questions you or anyone else can say about anyone else's project ahead of time. If the full featured parser is too big, then the line drawing the scope of the lightweight parser has to go somewhere, and so of course there will be things on the other side of that line no matter where it is except all the way back at full-featured-parser. "just this one little check" is not automatially reasonable, because that check isn't automatically more impoprtant than any other, and they are all "just one little checks"s. The one little check would perevent what? Maybe a problem that never happens or doesn't hurt when it does happen. A value might be misinerpreted? So what? Let it. Maybe it makes more sense to handle that in the application code the one place it might matter. If it will matter so much, then maybe the application needs the full fat library.
