Not really, even at “low” charging speeds you have more than enough braking.
Braking is the reverse of accelerating so the rate is about the same for the same acceleration (positive or negative).
It’s really only if the battery is extremely close to full that this is a potential issue, and that’s assuming the manufacturer either has little to no buffer, or didn’t take this in account and won’t regen into (some of) the buffer.

If the battery is hot and you want to accelerate, increasing the 0-60 time from 3 seconds to 10 seconds isn't a problem for ordinary usage. If the battery is hot and you want to stop, increasing the stopping time isn't acceptable so the car is going to use the friction brakes instead.
