I have no idea what yields are like on the different electric motors but it seems like the AWD 980/990 switchover was done as a production optimization. Assuming with improving production processes an increasing number of 990 motors can meet the output that is typical of the 980, the optimization could be as simple as having to test fewer motors.Makes sense. Yes, they gave you a P3D-, and converted it to AWD. They are switchable - though now it is not possible to switch an AWD -> P3D. It is only possible to do P3D- => AWD.
Good deal for you anyway.
In 2018, both switch directions were possible. Same motor was used in both.
We don't know that you can't use the 990 motor in the P3D-, but there is no evidence to date that it is possible. The 990 motor can produce more power than it does in an AWD (there's some examples in Europe with special software being applied, to what I think are 990 motors), but in any case the point is that it is distinctly different hardware than the 980 motor in the Performance.
The production optimization for the LR AWD trim might make it unlikely for Tesla to offer software uncorking of Performance, as only certain cars would have the motors that are safely rated for that output. It might not make much sense to have an upgrade option that is only available to "lucky" owners of a specific trim.
It's interesting that back in late 2018 the LR AWD <-> M3P- price difference was ~$9k despite many cars having the same motors, but now the difference is only $2k despite the motor separation.
I'm not sure what M3P+ part supply is like, but I remember reading about shortages of the 20" wheels over the course of the past year. The bursty influx of random M3P- cars might be as simple as Tesla not having enough 20" wheels, red brake calipers, spoilers etc. to go around and complete them. In this case I wouldn't expect the M3P- to disappear anytime soon.
