My idea is more for avoiding impersonations, rather than giving value assessments.

Hard problems 😅
Sure we'll incorporate multiple curators (so nostr:npub1r0rs5q2gk0e3dk3nlc7gnu378ec6cnlenqp8a3cjhyzu6f8k5sgs4sq9ac can use it).
Idea is to show various trust metrics (I also dislike scores) for the user to make a decision whether to trust/install the app or not. Domain names are fiat crap, sure, but they have value so they're shown. The app itself can completely change how trust is assessed, you might not care at all for an alarm clock app but care a lot for a bitcoin wallet.
But no matter how you slice it, the web of trust will ALWAYS be involved. Curators are simply someone you decided to trust. "Known people in the space" are also because people you trust, trust them and we need to validate that. I can assure you I can spin a full clone of the existent ~25k and ~180k connections in have in trustgraph and have Gigis, Odells, etc.
Re: avoiding impersonations, it's my next plan for trustgraph (i.e. probability of impersonator, given your 2-3 hop graph) - I was discussing that with Niel the other day.
