The user didn't want to rewrite the code to alter some conditionals, and
instead wanted Emacs to be changed so that they didn't have to do that.
I pointed out that the user can trivially just pre-process the data if
they didn't want to rewrite those conditionals.

(And they can just modify the structure in place if GC's a concern.)

I think the conclusion here is that we don't want to add :empty-object
to json.c, so I'm closing this bug report.
