I am not sure that it is much a win as the code loses readability for
a minimal refactoring. What would have been nice is to group as well
jsonb_delete_idx but handling of the element deletion is really
different there.

That's a good idea.

Looking at both patches proposed, documentation is still missing in
the list of jsonb operators as '-' is missing for arrays. I am marking
this patch as waiting on author for now.
