Reverse does make sense to me. I've lived for years in cities with steep hills, and also gone on gravel roads on hills, and reverse helps both situations.
Even just being able to back out of my downsloped driveway would make my daily life easier - I always perform a Y turn to back down into my driveway so I can easily get out in the morning, and I use low-speed regen and throttle to ease my way down. Being able to aim into the garage and then back out in the morning would be much more straightforward.
It's a reasonable option, just not for everybody's needs.
