Sorry for slow response on this…
I don’t think we will ever get a protocol-wide spec for WoT or consensus over how to apply it and where. Some feel strongly that it should only be on the client side, others (myself included) think relays are way better suited for these types of tasks (with some centralization costs). Others feel it should be separate from both in the form of DVMs.
I think it’s inevitable we see several different approaches and it’s apart of embracing the chaos.
