May I know your concern? My understanding is that ACPI may export
different interfaces according to _PDC evaluation. I think though ACPI
may export more than actually used, as long as nobody is playing with
the additional interfaces, there should be no side effects. Or these
interfaces may have dependencies or interactions I am not aware of?

Flexibility is good as long as it does not introduce too much
complexicity. It could have benefit of less compile time, smaller
size, less boot up time, etc.
