Hi Jeff,
Apologies if I am derailing your attempt at getting this support
merged, but I am actually proposing to the USWG to make this a config
table rather than a EFI variable, for the obvious reason that using a
runtime service to decide which runtime services are supported is a
bit problematic, and it forces the OS to invent its own way to
exchange this information between the OS loader and the OS proper.
A configuration table does not have this limitation, so it seems much
better suited for this.
