I can forward the arguments of the people who requested this functionality:

(1) Aleksei requested this fairly recently:
    <https://github.com/tianocore/edk2/issues/5>.

(2) I've seen arguments about the long-term relevance of
    Windows 2008 R2:
    <https://bugzilla.redhat.com/show_bug.cgi?id=1248758#c15>

    and of Windows 7:
    <https://bugzilla.redhat.com/show_bug.cgi?id=1248758#c16>

My own arguments:

- SLIC is actually governed by a public Microsoft spec, so it doesn't
  hurt to conform to it.

- We went to *much* greater lengths for enabling UEFI Windows 7 / UEFI
  Windows Server 2008 R2 on top of OVMF *without* a CSM. UEFI is not
  relevant at all in this thread, I'm just saying that in comparison to
  what we had taken on for the Win7 family's sake, this effort is almost
  negligible.
