I have no idea what you are trying to express here. "Trust On First Use" is a synonym for key continuity. The fact that you have to type "yes" when SSH does it and click a series of buttons when a browser does it doesn't change anything.

I think you think that "Trust On First Use" means "automatically accept keys the first time you hit a site". In fact, that's only true in practice. Presumably everyone's going to get the "Watch Out! This Could Be Iran!" dialog from their browser, too.
