Ok, so what is the primary reason? As far as I could tell it is
"Microsoft wants ACPI" and "hardware people want Microsoft" and
"fragmentation is bad so we do ACPI" (1) (and maybe "someone at RedHat
says they want ACPI" -- but RedHat people should really speak for
themselves.)

You snipped quite a lot of reasons why ACPI is inferior that were
below this line in email.

(1) ignoring fact that it causes fragmentation between servers and phones.
