The user has stepped outside the original trust model ("I trust anything
signed by Microsoft and only things signed by Microsoft") and into a new
one ("I trust things that I say I trust"). That's a great thing for a
user to do, but it also means that once the user's done it we don't need
to give a fuck about what Microsoft think. They're irrelevant once the
user's made that choice.
