I'm not aware UEFI has published any information on this.  I think the
shim-review repo predates UEFI ownership, but I'm sure the maintainers
of the repository can answer how they came to be trusted ...

... and how they handle the HSM.

However, if you're worried about risks to the integrity of secure boot,
I'd be much more concerned about the number of ODM motherboard
manufacturers who seem to have managed to lose their PK private keys,
or keys they placed into db, somehow ...
