In terms of things cars typically have on the wheel/stalk, on the Tesla stalk can only invoke rinse or a quick wiper clearing -- you can't turn wipers on/off, change wiper speeds or turn on/off auto wipers from the stalk.

fog lights cannot be activated from the stalk

Also you say that climate is on the steering wheel ---- Where is that? Unless you are talking about being able to invoke the speech command, which is a bit different

Other things like defroster activation is more of an issue of tablet vs physical buttons / controls
