Well, there's a lot of those lists and most states don't test anything other than OBD-II emissions readiness. And I don't really think that the primary concern here is that automakers are going to disable your brakes or legally mandated lights.
If it’s the difference between them getting your $50 per month network subscription you bet they will disable your headlights if given the legal leeway to do so.
The legal environment for motor vehicle torts likely already makes that a losing game to play.
