I used to think I wanted that until I had to use separate knobs for hot and cold water and it was even more fiddly, you also have to get pressure correct. They ended up leaking and I figured it was just easier to replace with a turn handle fixture that uses cartridges than learning how to repair super old plumbing, the handle is actually way more forgiving in terms of getting it in the range of tolerable temperatures, and you don’t have to think about water pressure.
Just turn on the hot water first to desired pressure, then turn on the cold water to get temperature
Edit: because you really don’t need much cold water to cool it down.
Edit 2: then as the shower cools down over time, just turn down the cold water a little bit as needed
Edit 3: and because you’re able to control overall pressure, you can have exact temperature to a trickle or full power, allowing you to have as long or powerful of a shower as you want
