Just to throw my two cents in here, yes, I feel it would be best if the
server's behavior was compliant.

In the situation of master->secondary communication breakdown that's not
immediately noticed, it would be preferable (to a measurable percentage
of us, at least) that the broken secondary server stops being
authoritative rather than provide out-of-date information.

If the user doesn't like this behavior, they have the option to
configure the expiry time to a very large value.
