Thermostats are made with way more granurality than needed, like body scales with 100 gram/quarter pound precision or battery testers with millivolt sensitivity. Most people have single zone HVAC with one controlling thermometer, and it's literally impossible for the whole house to have uniform temperature. And yet, most people are fine around the whole house, not just where the controlling thermometer is. I still don't get why are you so fixated on 50°C. Why not 125°F? You'd get even more unused range if you go 0-125.
