That seems quite backwards to me.
Why should we consider that a good thing?

I discussed this with Andy Grover and he said that the DSDT isn't
where the memory size is defined. It should just be coming from
the e820 BIOS calls, not from ACPI DSDT etc., which certainly
made sense to me, as that is something that a user wouldn't need
to modify after changing the memory size of a system.
