I don't understand (or agree with) this point at all. It's funny that you present turning creep off as "pretending" something -- surely turning creep on is a way of pretending that you're driving an automatic ICE with a torque converter? In any case, creep or no creep, the points you raise are fully addressed by automatic hold, at least when it's working properly which apparently it's not for OP but is for just about everyone else who's posted (including me).
So read the post that I was replying to. The poster was talking about a car slowing moving when on inclines. This suggests that somehow the poster thinks that the car should hold at a stop, this suggest that the poster thinks that it is one pedal driving, which it doesn't have.
Creep is easy, but people read all sorts of things into it.
Creep on = automatic transmission
Creep off = manual transmission
Regen has nothing to do with creep.
Pushing the brake and setting hold is a feature that I think Subaru started, if not just popularized and I had in my 1981 Subaru wagon.
My 2018 Leaf has one pedal driving in which when you lift your foot off the accelerator, it comes to a complete halt with brakes applied, it will not move on inclines.
Turning creep off in a Tesla is just like a straight shift in neutral. Except that the car is going to slow a little faster due to regen, but once it gets below a certain speed, it's just a car in neutral.
Turning creep off has been equated by a number of people on the forum as one pedal driving, that's just not true today.
