What "vendor" is there in this case? You released a signed shim, as did
the Linux Foundation, and lots of distros are now using it, and there
are absolutly no "orginization" behind a bunch of them. Will your
signed shim be revoked because a random PoC was posted somewhere that
could be used with any kernel booted using it?
