Figuring out how to make this usable is def a challenge, but it’s one that we desperately need to figure out, at least in my opinion. The value added would be tremendous once it’s all in place.

Shifting from scraped data (which is based on the oftentimes false assumption that follows = trust) to explicit trust claims is one of the humps we need to get over. The question is: how exactly do we do that?

Perhaps for starters: for a marketplace, make a hierarchical list of product categories. Since it’s hierarchical, instead of rating all your contacts in a super granular fashion, which would take forever, you could use large categories. Probably for starters, Alice would say she trusts Bob in “all categories”. She might even just want to port her entire follows list, saying she trusts all her follows for all categories. Of course the point is that that’s not always true, so the next thing she can do is edit the trust ratings, in as granular a fashion as she desires.

To address your point of x’ing out of the checklist: display an option at some point where the user ports the entire follows list into a “trust in all things” list. Make it easy and painless. That’s just to jumpstart the system. When Alice later realizes she doesn’t actually trust Bob in category X, that’s when she discovers she can provide an updated attestation to that effect.
