Hi @sebastian, thanks for the feedback!
These both could be pretty complex (specially the API) and would thus end up as strategic, roadmap-level items (as opposed to some minor enhancements); we'd already have ProGet v2022 mostly planned out, so it would be a bit before we can consider it.
How's your relational database / SQL skills? If you're comfortable exploring the data in there, it might give you some insight / ideas into what we can do as a low-risk, minor-enhancement that would add a lot of value. Once you're able to see what is possible with the existing data, then it might be a view we can do.
We don't have a "guide" on how to query the tables, but we can assist if you have questions. The database columns should be familiar, but tables of interest: Vulnerabilities, FeedVulnerabilitySources (links feeds + vulnerability sources), and PackageDependents (package consumers).
Thanks,
Steve
