Its actually more like getting a 2020 car in 2021, one that has features designed for make it easier for mechanics to work on, or take up less space in your garage, at least in my opinion.
Powerwall 2s are still being installed right now, so its still a current product, and it appears to me that the main differences have to do with "less boxes on the wall, if the authority having jurisdictions (AHJ) allow.
You likely wouldnt get the gateway as well, which has a 1100 value. If I were getting a referral powerwall, I would want the regular one and the gateway as that would be easier to get installed OR to sell if I was so inclined.
