You're right, it is standard for cars in general, but that's my point. I can't say it's the case for all modern makers, but the one reference I can go off from is polestar and it has all that shit figured out and it's a new EV company (mostly/kind of at least). I don't know if its the same for companies like Tesla, Rivian, Lucid, etc. There's no reason not to change the dash settings when that's all stored in a computer now unlike back in the day where the head unit and heat controls with separate entities entirely from the seat settings. It just seems like a hold over from how things used to be done.
I know the shit I laid out are all updatable with a software update to add toggles and I've heard guesses that that fishtailing is an issue with torque vectoring or something (bad tire choices could be part too, but it drives fine in snow). Its still a problem for a legacy vehicle maker that should have it more figured out than they do right now.

Lol fuck that
