Hi Kevin,
Thank you for accepting them.

The problem here is the QEMU series depends on it,while this series
doesn't depend on QEMU.
If no extra roots are present, the functionality is preserved as it is today.

I was waiting with the QEMU series to see the depending code getting accepted,
the depending code being this SEABIOS series and ACPI dynamic one that already
has a PULL request for it.

My main concern is the possibility for reviewers/testers to try it without too much work,
but I guess it doesn't really matter.
