I think the attraction to the SafeString example is that it's simple and
effective for the task at hand -- in other words, pragmatic. Suggesting
that in order to avoid HTML injection people re-read the HTML spec and
invent a complete ADT to represent all the little corner cases they
probably won't ever use is exactly the kind of answer that would scare
Joe Six-Pack Hockey Programmer away.
