Does constant regeneration lessen the longevity of the motor

Not that I can tell. Regeneration is typically a short event and even coming down a mountain, no problem.

The only risk I can see is if you start from the mountain top with a full battery charge, there won't be any 'head room' to absorb the regeneration energy from the motor. The control laws would require using the mechanical brakes.

And I think most EVs -- my Kona, for example -- flash a warning telling you no regen is available and you need to use the brake pedal.

Both my MINI Electric and Honda Clarity PHEV use the brakes to simulate regen braking and the BMW and Honda designers decided no warning was necessary.

Interesting. If you get essentially the same effect, I don't think it really matters safety-wise not having a warning. With the Kona the warning is useful if you've gotten used to the effect of the regen. We've strayed a bit from the original inquiry, but I've never read anything indicating that use of regen has negative effects on the motor.
 
Anecdotally, I've got over 94,000 miles on my MINI SE and still on original brake pads because I use regen as much as possible. No sign of degradation, but as @insightman pointed out the car takes care of a full battery situation automatically.
