In theory yes, in practice ACPI isn't always a great solution (as can be seen by the many lines of kernel logs about broken DSDTs on my motherboard).
Manufacturers kind of suck at actually describing the hardware on their motherboards and hacks and workarounds are very much required to provide a usable experience on many machines.
Unless manufacturers stop lazily copy-pasting their DSDTs with minor changes, we should probably hope for a better solution.
