My $0.02: I would expect || to be what I want to use to add something to
an existing JSON document, no matter what the path of what I'm adding
is. In other words, deep merge. I certainly wouldn't expect it to be
shallow.
If we get this wrong now, we'll be stuck with it forever. At a minimum I
think we should use anything other than || until we can figure this out.
That leaves || available for whichever case we decide on.
BTW, if people are set on shallow merge being || then I'd suggest ||| as
the deep merge operator.
