Isn't the issue you're describing less about the OS and more about cheap keyboards with awful or nonexistent NKRO? On my keyboard with full NKRO I can press as many keys as I want and the OS will recognize all of them being pressed without fail.
Also, if I'm in a text editorand hold down one key, then start holding down another one, the new one is immediately picked up, which is pretty much identical to this situation.
"A single company does this and while the other 99 won't, saying pretty please will certainly work. See? No intervention required!"
Bootlicker indeed.
