Hi Simon,

6) Sigstore and Sigsum.  (I hope I provoke both camps here too :)) These
are modern designs that realize that signatures without transparency is
not effective against practical attacks.  Reasonable well specified,
although lacking in multiple implementations and PQ options.  Sigstore
suffer from complexity and its focus on container security.  Sigsum
suffer from lack of non-Go implementations and MIME integration.

Doesn't Sigstore require a centralized Rekor instance? That was the
impression I based on a very brief look at it previously.
