Where is my custom mechanical keyboard that has every single XF86 multimedia keys?

@320x200 Do you know how many of these really work with popular software?

@praxeology not many I think. Laptop keyboards usually have a couple, varying from model to model, era to era, brand to brand. BSD/Linux Desktop Environments make use of these to provide out of the box functionality for things like increasing/decreasing brightness/volume out of the box, or turn ON/OFF stuff like BT/WiFi. If you just run a windows manager, you need something like xbindkeys or sxhkd to turn the key press into whatever you want. But under the hood, it's all there, with xorg/evdev/libinput lurking in the dark waiting to see if they recognize a particular hexadecimal keysym generated when a key is pressed. I haven't looked much further but wouldbe curious is there are any traces left of meetings/standard drafts that led to decide on all the potential keys, or if there is some sort of procedure for a manufacturer to add a new one. I also wonder if some of these are there simply because of super special hardware that needed these mapping at some point.
