That's okay, we can start by making this an optional feature, and
consider making it the default after a couple of major releases;
meanwhile, any problems will be detected and reported.

However, it would make much more sense to consider switching to this
code if it also could handle producing JSON output, thus making
libjansson unnecessary when we decide to switch.
