If I may, two suggestions:
1) Allow the user to filter for plugins based on the desired level of strictness (manually reviewed, safety rating, etc).
2) The Disclosures seems a bit too lenient. For example, the popular Templater plugin [2] gets a 92 rating, with Excellent Health and Satisfactory review. But the disclosures are pretty concerning: dynamic code execution, network calls, wasm blobs, malware scan not available, etc.
I know it's tricky to boil this down to a single numerical score that works for everyone, but I think the bar needs to be higher than this. And Plugin developers should be held to a higher standard (e.g. don't use eval()) or at least thoroughly document why you need it.
