I think the argument would be that consuming Minimus' containers would have a less severe amplification (or even reduction), as all upstream attacks that rely on a combination of third-party vulnerabilities would be rendered infeasible (since they reduce the amount of third-party dependencies in an image).

> 3. This ties into 2, if someone downloads and uses an image that is later found to be compromised they mostly have no way of being notified that happened.

For this you need a consumption-aware scanner anyways (e.g. that lists images running in your Kubernetes). Anything else will be too spammy, as you can't notify for everything for you have at some point in time have used as a base image.
