I wouldn't mind if Unity 2022.3 was the final version of the product. Nothing about Unity 6 is interesting to me. If I want more than what this old build can offer, I'd go find a big cash pile, hire a team and roll my own engine.

The only thing that would make me want to upgrade to a newer version is if they get CoreCLR working. Even then, I don't think there is much value add for the project I am currently on.
