2. Isn't there a slight risk of upstream attacks being amplified by this? With the recent number of software compromises providing a way for people to use images X days old may be useful.
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. Not a huge issue, but is something that should be risk assessed.
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).

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.
For example, with EE, you can create an action to automatically trigger a webhook or send a Slack message when an image you're using has a critical CVE that's likely to be exploited (we also integrate threat intel from EPSS, KEV, etc).
Definitely still value in having runtime scanning / visibility too, but EE makes it easy to do purely on the 'left' side of things too.
