The PCI domain maybe larger than 16 bits on Microsoft Azure and other
virtual environments. PCI busses reported by ACPI are limited to
16 bits, but in Azure the domain value for pass through devices is
intentionally larger than 16 bits to avoid clashing with local
devices. This is needed to support pass through of GPU devices.

Isn't that going to break the ABI?
