You're both right, but in different contexts.

Chris, a policy without a list of exceptions is clearer than a policy
with exceptions. Calling out legacy addresses specifically makes them
an exception.

But here's the context: legacy addresses are an exception. Even before
a proposal author writes the first word, legacy addresses were an
exception to ARIN's normal rules. So if he intends a policy to impact
them, it is appropriate to call that out... lest folks (reasonably)
assume that legacy addresses are an exception to his new policy as
well.

Bill Herrin
