Right. However, note that this only affects one patch in the series
(patch 3). Patches 1-2 are useful to unify Xen-specific behavior with
other hypervisors, and patches 4-6 are useful to future-proof ACPI table
sizes for migration.

I agree. However, we need to cater for a fixed initrd loading address
until this is done. And even after linuxboot.bin is improved, the older
version will be used when migrating for older QEMU machine types, so it
is important to have a decent fallback.
