I've been doing that for a while with my own car because their API (like other OEM's) is just an OAuth2 REST API with unofficial documentation. So I think this is more "Tesla is launching their developer API documentation and officially letting people develop against it".
Fwiw Tesla's has been the best to work with in my limited experience. Ford's is also decent but the most important remote commands (like start/stop charging) seem to be hidden behind obfuscated endpoints. I spent quite some days trying to reverse engineer them but ultimately gave up.
