Quake was released in 1996 and if I recall correctly at the time the arrow keys were the standard but one famous Quake pro player used WASD and it helped launch it to today default.

My point is, I don’t think it was ever OK to not have customizable keyboard controls, and having it also give you permission no be perfect in your chosen default. I understand not including the option to have multiple keys assigned to the same control (although I don’t excuse it because it is not rocket science), but not have configurable controls at all? It was unforgivable in the 2000 and it is exponentially more unforgivable today.
