That's a great point. All the use cases we cite for \& -- inhibiting
kerning, inhibiting beginning-of-line control characters, inhibiting
end-of-sentence detection -- are accomplished by any escape (printing
or not) appearing in that spot. The property that sets \& apart from
all these others is that it does nothing else besides this: it's
no-opness.
Another advantage of the term "no-op" is that it makes redundant
qualifiers such as "non-printing." If it does nothing, then that
automatically includes not printing anything.
