Agree with what you said.

This is not exhaustive, but a few essential elements:

- explicit trust attestations need to be contextual
- trust (or lack thereof) in a broad context automatically implies trust (or lack thereof) in all subcontexts 
- the list of contexts and their relationships must ultimately be curated by one’s web of trust (but ok for devs to manage these in early product iterations)

We don’t need to roll out all of the above in one fell swoop. We can and should roll them out in baby steps. Builders who know DESIGN and who know PRODUCT will be CRUCIAL in figuring out how to roll things out, one step at a time, in a manner that will be accepted by users!
