Changeable decision.
And I want to insist on my suggestion regarding trust: guest should see some trust.
The main reason that I went for [the DT1 modification] 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.
