The adapters shouldn't be a big deal. All new Teslas are able to use the CCS protocol over the NACS port and any new chargers implementing NACS will likely use it as well so any dumb adapter should work perfectly fine with a 3rd party NACS charger. GM/Ford additionally may have some special sauce that will let them use superchargers but that's somewhat of a separate issue.
