After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
I think it comes down to driver support. It’s not that the hardware can’t do this, but rather it’s that you need to pass the option to control it all the way up from the lowest levels of the system eventually into user space where you can select an option in settings.
That, and it’s just not the first priority on devices that are generally low-margin.
