It looks like that does the same basic idea of delaying driver binding
that this series does. Hopefully Leon can harmonize it to use the
shared trust level flag instead of a usb specific flag and retain all
the uABI around it.

But, even with this v1 the user can choose to use the generic trust
level and ignore the USB specific authorized and get the same
functional outcome.

Yes, we are investing alot of time right now in trying to get SPDM
uAPI right when we bring the general framework into the
kernel. Everyone needing SPDM should be able to re-use it.
