One goal of the boot wrapper is to be as simple as reasonably possible.
ACPI support in the boot wrapper would be far from trivial, at minimum
requiring EFI support (requiring either a whole reimplementation, or
work to make EDK2 run atop of the boot wrapper).
Given that it is already possible to use ARM Trusted Firmware and EDK2
in a model environment, and this can already be used to handover ACPI
tables, one would be served better by those.

That is the canonical repo these days, yes.
Thanks,
