No, at least not with that reasoning. These are two different games, and DC is free to do things its own way. You can remap your key bindings as you wish from the options and that should be sufficient.
I don't think he's being that unreasonable. He can remap a lot of the keys true, but the production and unit ability hotkeys are not remappable as far as I know. Some people prefer the grid system. I'm not one of them myself. but I can understand their point of view.
That said, it's not that urgent an issue.
