RFC 4627 is from 2006 and is obsoleted by RFCs 7158, 7159, and 8259, as
well as both versions of ECMA-404, since at least as far back as 2013,
all of which lift the strict object/array restriction.

The current json.c produces maximally compatible JSON text in that all
implementations must accept object/array text, but it would be nice to
support scalar values too.
