And UEFI/ACPI currently appears to not give anyone anything
to support (yet).

which was just released in March 2020 and only recently updated
as of 2 months ago.  I assume the other type 1 are the named
components for the network packet processor.  Those will need
to be fixed once driver support for the onboard networking is
added

(Jon is not always clear about UEFI/ACPI vs. U-Boot vs.
Linux kernel or whatever combination is involved.)

I've never been one to spend effort cutting things from
the standard kernels. In a couple of cases, in dealing
with old PowerMac issues, I've forced something to be
in the kernel to avoid contexts where I could not load
the same but it was always needed for what I was doing.

The PCIe slot has an Optane, not video. Very few of
the machines I use have video engaged even rarely.
One FreeBSD machine has a lower end (and low power)
video card --but I do not use X11 or the like on it
generally. Similarly for built-in HDMI (when it is
used at all).

The same Optane can be used to boot the MACCHIATObin
Double Shot, where it was previously in use. I do
not have access to other aarch64 machines with a
PCIe slot. These two machines only have one such
slot.
