I need to answer this directly. This is better because vendorA is forced
to collaborate with vendorB about instantiation options. No more "stick
new feature that might be duplicative in a siloed driver in
drivers/virt/coco/$vendor". This is better for the kernel.

Once standardization materialized this is already ahead of the game
providing a front end to instantiate that common format. This interface
choice forces ongoing community collaboration on how options are
presented. It takes a position that all existing options that sevguest
already exports are in scope and provides a place to have a discussion
about how and when to add more options. This is better for
collaboration.
