Yes. We have received feedback on lack of clarity regarding many memory
attributes in the UEFI & PI spec (e.g., capability versus settings, etc). I'll
work w/ the UEFI Forum to clarify in upcoming errata on those documents.

Good question.
Code has been public in a zip on http://firmware.intel.com for some time.
We have received feedback on that zip from coreboot community & others,
including Stefan, that helped inform moving it to live SCM on tianocore so that
it can be evolved with the community.

I agree. I would keep the original .asm and .s, along w/ new .nasm, at
least as part of a transition period of engagement w/ the community.

Good points on both sides.
I see UEFI Forum w/ USWG and ASWG (UEFI and ACPI spec, resp) as a place to
explore this a little further, although Fish may be right about ultimate scope
boundaries.
As such, I’ll take the action item to convey these concerns to those bodies
this upcoming week.

Ideally we could do it in the Dxe Core prior to Bds Entry invocation. In
practice it is done in the respective BDS prior to doing connects and
invoking 3rd party UEFI drivers.

Yes. You can create ROM'd page tables for a long-mode transition in SEC
prior to invoking a 64-bit PEI core. As implementation guidance, make sure
to set the access/dirty bits in the ROM'd page tables in code source code.
