I am mildly against this, as long as you feel that all the remaining
steps need to be marked with "(optional)", because this will give
readers an impression that somehow single-quote is special.  If we
do not intend to make it special at all, we shouldn't.

If we do commit to make it special, then this is a very sensible
first step that is backward compatible, of course, and I find that
the following steps form a reasonable transition plan, if we intend
to follow all the way through.
