There is an Elisp library `json.el` that comes with Emacs, which is also 
available in Emacs 26 (and perhaps earlier versions, dunno). But it's not a 
drop-in replacement, because the functionality of the two isn't entirely 
equivalent (and function names are different). So if `osm` isn't set up to work 
with it as an alternative, native json support is gonna be necessary.
