Steve,

Your suggestion to generalize this tag makes more sense to me than Ted's
CP, but only a little. In the first instance, we should have some
legitimate use cases for it. But, more importantly, we should consider
whether providing an auto opt-out tag is what we really want to supply.
Do we really believe site developers know more about what is legitimate
to exempt from checking than the standards development body that has
painstakingly developed their standards? Why would we believe they'd
make intelligent decisions about privacy, security, i18n, or a11y? Isn't
that simply ceding the most important reasons for user-centered
standards? If we're going to give that power away, why bother developing
the specs in the first place? Because, by so doing, we reduce them to
suggestions of convenience.

I, for one,  don't trust my accessibility to some developer's
convenience.
