I was having the same thought, but switches do require something like ESP32 to emulate keyboard. So I settled to this: 11.86€ 44% OFF|16/20/24 Keys Mini Mechanical Keyboard Macro Custom Shortcut Programming Keypad Osu Gaming Keyboard For Windows Macos - Keyboards - AliExpress
That thing is amazing, you can configure it for any type of shortcut (or even mouse actions), or makro, or skript almst anything really. Also every button has configurable RGB led. Settings are stored in the keyboard itself. Now I have to figure out what UI actions do I need to map it in WebConf so it would be as close as possible to official kit. Someones are obious (like arrors, select and back), others not so much.
