Comment(by mrada@…):

 I don't want to modify json either, but I don't think we can fix this
 problem without making at least one or two small changes.

 You have already made one change before that we have to revert, but is
 blocked by #1326.

 I would prefer the least conceptual change, which is what I linked to
 earlier in my MR fork; but the alternative solution I proposed would be
 contained to a single file where we modify a single method.
