Theymos have already spoken that he intends to allow guest to visualize the trust. And it seems to me that he should expand to other sections as well. Trust has never been just a business issue, in many cases it is a matter of trusting the information offered by that user.
The main reason that I went for this solution rather than forcing custom lists is that I would like to show some trust indicator to guests. But before doing that, I want to see whether these modifications can actually be made to work. If not, then I may go to the force-custom-lists solution, and that's incompatible with guests seeing any trust indicators.
