If you have specific suggestions for alterations to the current DT1 list, then make a topic about it. I think that the system is structurally flawed as it is now, though.
Here's my specific suggestion: Add me to DT1.
Why?
If DT exists, I would want it to be a list of people who are unlikely to scam others, and nothing more. My DT2 additions would not be ultimately trusted people, but just people that I feel are trustworthy enough to be unlikely scammers. I've been in this scene for years and have seen many kinds of scammers and people in general, also having moderated bitcoin IRC channels for years and recently bitcoin subreddit too.
So in other words, I would want to decrease the "legitimacy" of the DT list as an "elite, highly trusted people" list. This would encourage people to make their own lists. I would be adding loads people I've got to know over the years, and I am sure that many do not find them trustworthy to e.g. do trades, even though I do. It should merely be a list of people unlikely to scam others, and that's how I would treat it.
Additionally, add bunch of current DT2 members to DT1 so the DT1 gets "diluted" as it should.
