I strongly disagree, and have written a draft that would provide,
among other things, what I believe to be such a mechanism (though some
people on the W3C websec list seem to disagree, because they want
assurances that are not currently provided by the public suffix list).
The draft has heard some support from various reviewers, but I'm still
not sure where next to go with it, so I haven't been flogging it.
Review is welcome, however.
