json.c is a lot less "DWIM" than json.el -- which I think is generally a
good idea when it comes to doing round-trips between Elisp and JSON,
because you avoid a lot of corner cases.

So I'd be inclined to just regard this as a feature, but I've added
Philipp to the CCs -- perhaps he has some comments.
