Yep. I think this makes a lot of sense. Since Tesla is apparently at the point where they are close to releasing their FSD software package, it is to their interest to get as many Tesla owners on FSD as possible for the reasons you mention. More FSD cars mean more data which in turns means getting to L4 faster. And to your second point, ultimately I think Tesla wants as much uniformity as possible in their software to keep things simple and make software updates easier. If they have AP1 with and without autopilot, AP2 with and without EAP, AP2.5 with just EAP and AP2.5 with FSD, AP3 with FSD, it's get confusing for their software updates.
