Adding configurability is a good additional option (even outside the layout detection) but because people like different layouts not because a few HN style folks break OS detection via custom firmware. It's certainly not a reasonable cause to redesign your control scheme around the limitation either. Something of 10%+ of internet users don't use qwerty, something of 0.01% set their layout via the keyboard's firmware. Good note on the game being released ~2015 though, the API wasn't added until ~2018.
