This construction is baroque, grotesque, and insecure.  It is simply
unwise to allow an arbitary content provider to have this level of
control over a user agent.

Moreover, it presents challenges for public sector content providers
who by law cannot allow the impression of being unduly influenced by
particular market participants.

I hope we can persuade the purveyors of user agents offering such
constructions to join with others in providing a better approach that
is both secure and inter-operably meaningful.
