Most BEVs do regenerate power from the wheels when the driver releases the accelerator. For some reason this mode has been popular, I think because manufacturers believe (with data or not, I'm not sure) that this encourages drivers to make better use of regeneration, because hard braking will obviously make use of the brakes, and many drivers do not drive particuarly....smoothly. This is also not without precedent as it mirrors the engine braking effect you can make use of with a manual transmission.
I personally don't like this mode, but I am also generally aware of how to brake gradually, and I plan my stops well in advance, as a result, this mode requires me to feather the throttle to coast the vehicle, which is significantly more complicated than just releasing the gas.
Yes, I meant more significant as a percentage of battery capacity.
My recently-sold car (no, not EV) was still on original brake discs after 9+ years, courtesy of gradual slowing down, frequently with no brakes needed. It's really not hard to do once you get used to it, you just need to anticipate the need to slow down some more.
