Mine seemed to work right away on 40.1 ? At least I didn't see such a message warning about it not being available, and it was definitely working by the time I got on the highway (1-2 miles or so from home).

It's more complex than that.
The AC can't chill by just a degree or two, it chills be a fair amount relative to the intake temp. If you need it only slightly cooler then you need to mix in some heat to get the desired temperature. Some of this may be waste heat from the rest of the car (motors, inverters, AP computer, etc), but if more is needed to balance the temperature to the desired temp then the cabin heater will be engaged too.
It would be nice if we had the option to disable cabin heater (but still use waste heat) just as we do to disable AC itself. If you were willing to have less consistent temperature control, it would increase your range when the temperature is otherwise only slightly warmer than you desire.
Are you sure? I thought the waste heat loop was tied in to the refrigerant loop? Even if they don't route the waste heat directly to the cabin, wouldn't running the waste heat by the refrigerant heat exchanger whenever it's running, instead of using the regular radiators, have the same effect of offsetting the amount of cooling delivered to the cabin?

Seems like Nav on AP was removed, or am I missing something/setting somewhere.

That notification shows up if something is wrong with your cameras. Try cleaning all your cameras and see if it goes away. If not, then you'll need to take it in.

Pretty sure admitting that I am a member in the early access software program is not discussing the build. But thank you for your concern.

I'm on that build and I haven't noticed any issues with locking or unlocking the doors to trunk via phone key. Slacker works as well as it did with 2018.36.
On a side note, I took 39.7.1 on an extensive trip this weekend with AP to LA and back, and it worked pretty well. No "ping ponging" although there are some hairy places on the 101 (older, more twisty highway) that it seemed to struggle. No jumping at shadows, which was good. The TeslaCam worked great the whole weekend, then quit this morning. Gotta figure out what happened there.

My Model 3 has never been on Wi-Fi since I got it in June. Usually it takes many weeks after a software release is going out before I get it. Yesterday, I got V9 (2018.40.1 09acee2).
The Model 3 at least can take heat out of the glycol loop :
While that doesn't mean that heat is transferred directly to the cabin, it will increase the heat load on the refrigerant loop, decreasing the amount it can cool the cabin. Perhaps they don't explicitly make use of this to avoid using the cabin heater, but any time the powertrain or battery is seeing a lot of heat load (more than the regular glycol radiators can handle, and thus causing the refridgerant loop to be connected to it to cool the glycol loop), it will impact how much cooling the refrigerant loop can provide to the cabin. So if they're not using it intentionally in this way, it should only take a software update to do so.
