There's an annoying market trap here. In-wall stuff almost always means an electrician is installing it, so companies there target whole-house systems with custom wiring, which is only relevant for rich folks. Because this moves at architect speed, these systems are generally still dimming only, and if you want full color, you're looking at stuff built for professional event spaces. All of the nice wireless color stuff is targeting the lowest possible bar for end user installs, which means switches can't be attached by anything other than a command strip and have to be battery powered, hence removable.
There's no reason why someone couldn't make a box that replaces the in-wall switch, leaves the circuit always on, powers the transmitter off wall power, and gives the user nice firm predictable tactile buttons like they're familiar with, but it would need a lot more regulatory approval and in make markets a professional install, so it would cost ~8 times as much to the consumer, making it a specialty product relevant for maybe .5% of their customers, and thus not worth building. It's also a conceptually weird object, so it would take a lot of user education, making it a hard sell even for that .5%.
And thus, the world will continue to be awful.
