I know I'm not but according to the numerous statements I read about the trust system, there's no reason this would be breaking any rule

You would have to be directly put in the DefaultTrust list by theymos himself to be at depth=1 though
Otherwise you'd be at depth>=2, so your own trusted users would be at depth>=3 in the DefaultTrust list, so people with original settings (DefaultTrust and depth<=2) wouldn't trust those
