There are a bunch of reasons why it wouldn't be worth implementing, but it would be cool if you could tell it how long you thought you would be in the store and it could adjust the charging time to be a bit gentler on the battery.

I'm sure it wouldn't get used much (unless the UI was very front and center, and maybe recommended a time based on your previous stops at that charger), and Tesla would be somewhat disincentivized to build it anyway as their goal is to get as many unique cars through the charger as possible, but it would still be neat...

I'm unsure if there is much difference between charging at 50kw vs 150-200kw wrt long term battery longevity (I have primarily supercharged my 100D Model S for ~140k miles, and only experience ~7% pack degradation), although I do pick the V2/150kw chargers to let folks potentially under a time crunch use the V2/250kw chargers (when the station has both due to legacy posts that were expanded, which is common in the area I currently frequent). Also, better to turn the stalls over faster considering amortized capex costs (charging fast = less stalls needed).

We're somewhat spoiled that aggressive volumes of fast DC charging is immaterial on battery pack health in well engineered battery packs, as well as the rate of improvement in battery technology. Don't worry too much about it, enjoy a better UX and simply charge when convenient. Batteries are only going to keep getting better.

There are enough stories of taxi/uber drivers who basically only charge at superchargers getting 200,000+ miles out of their Tesla battery that slowing down charge speed to optimize battery life is a minor optimization at best.

What would be really nice is a better way of sharing a charger after you're done charging. My experience is that a Tesla supercharger is often too fast. On a road trip charging stops usually coincide with meals, but a charge takes less time than a nice meal does. The charge is done and idle fees start accumulating when you're halfway through the meal. It's rude to others waiting for the charger to leave it there plugged in. It'd be awesome if there was a way to have two plugs per charger, and a big green light to indicate that the first car is done charging so that anybody pulling into the second stall would get a full speed charge.

That's essentially what they already do. The power feed is shared between neighboring chargers which is why you should leave a space between if there's empty stalls.

e.g. a 250kW charger becomes 125 when two cars are parked next to each other.

It only takes a minute to move your car, I don't really find it that big of a deal.

Not if it takes 10 minutes to walk from the restaurant and back.
