Hi Walter,

I agree with you that the logical solution would be to store them together
in the UA preferences.  From what I understand, though, the major UAs
would likely not implement this, though.

I probably should have spotted that in the list archives before, but
have missed it. I cannot speek for the UAs, nonetheless all research on
user opinions on tracking suggests that they are much more inclined to
go for a all-out DNT:1 than for DNT:0, which makes me assume that any
exception mechanism is unlikely to be used often. Sadly not all research
in this field is publicly available, so we have to make do with what is.

What credible research can you cite that is publicly available? Unfortunately we don't have much useful information on what users really want, or would want if they properly understood the technology and their choices. And it's certainly not very helpful to cite research that isn't available.
