Agreed, but ...

... I don't think that's an improvement. We don't document detailed
behavior of a datatype's functions in datatype.sgml, and this seems
like it would be contrary to that layout. If anything, I'd merge
the other way, with only a very minimal description of jsonpath
(perhaps none?) in datatype.sgml.

While we're whining about this, I find it very off-putting that
the jsonpath stuff was inserted in the JSON functions section
ahead of the actual JSON functions. I think it should have
gone after them, because it feels like a barely-related interjection
as it stands. Maybe there's even a case that it should be
its own <sect1>, after the "functions-json" section.
