PS1, Line 14: 	  Choose this option if you have PCH-N chipset.
> This is a config to control the compilation specific to ADL-N. […]

It would introduce lots of unnecessary complexity. Mainboards only use one type of PCH and it's always the same, so this is a compile-time constant. Yes, someone could choose the wrong PCH type when adding a new mainboard, but that would be their problem.
