I am "neutral" on this particular rule.

OTOH, my opinion is that we really should try to enforce the rules. The
fact that we are humans and make mistakes (some patches not enforcing
all the rules are committed), is not enough to just ignore the rules. If
a rule is not enforceable, it should be removed from CODING_STYLE, not
removed.
