No but there are always multiple supercharges at each station.

> it'll make sense to just designate the last 10% of battery as "reserve" and not count it in the battery level indicator.

Very questionable? Why would you do that?

We don't do that for gas cars either.

Every ICE car I've ever driven did exactly that with the 'reserve' where the needle is already at (or below) the zero line but you still get about 50 km of range.

I've been wondering about that with the cars with digital displays, particularly the ones that report your estimated remaining miles.

I once, embarrassingly, found myself on the highway with an empty tank of gas and 20 miles to the next gas station. I watched the estimated miles remaining indicator tick down mile after mile, ticking precisely my passage. At 3 miles estimated remaining, I pulled over because there was a very wide safe shoulder, and I didn't want to putter out in a less-safe spot.

I don't want to try the experiment of letting it tick down to zero and seeing if I still have 10 miles or so left.

Yup, exactly that.

I think the use cases for field-swapping a (part of the) battery pack are the same as for carrying extra fuel canisters with you, which I can only speculate about, because I've never been in such situation with an ICE car.
