I think I lost track of what problem you are trying to solve: is it
the security issue, or is the the problem Ping stated ("you cannot
know the full lexical rules by heart anymore").

If it is the latter, I don't understand why the 95% ascii users need
to run additional verification and checking tools. If they don't
know the full language, they won't use it - why should they run
any checking tools?

If it is the security issue, I don't see why a warning wouldn't
address the concerns of these users just as well.
