Thanks @laurentsimon ! What's the milestone deliverable plan for these features, v1?

Created the following issues to track here as well:

• Add support for Sigstore's private key signing flow #207
• Add support for using a private Sigstore stack #208

Thanks @laurentsimon ! What's the milestone deliverable plan for these features, v1?

I think these will get prioritised after the first v1 release, unless someone contributes them before.

+1 to having these after v1, for v1 we should have 1 end-to-end sign and verify flow and everything else is bonus
