I think that's how Subaru implements the hill holder for stick shifts.
Some people also don't have good upper-body strength. I drive a friend's car frequently and when I park it I just zip it up, but he can't release the brake while seated normally. He has to lean way over and two-hand it to get it free. When he parks it I can take it out of gear and budge the car forward if I lean on it enough. Perhaps a better designed lever would help, but an electric brake would eliminate the problem for him.
I still prefer a simple lever.
