I think they should have it so there's a type of "slow down" light that supplements the brake light for when your deceleration is from taking your foot off the gas.
A few times I've had to use my alarm when other people are sleeping and it usually wakes me up (because I'm used to it) without waking anyone else up too.
They might need to check their assumptions. It might not feel like the brake is engaged but it's an expensive habit that causes unnecessary wear and tear. https://drivingmecrazyblog.com/2020/02/07/quit-riding-your-brakes/
