Yes, which is exactly the same effect as telling first party sites
that they should collect as little data about the user as possible
and not store anything after the session.  My point is that there is
no need for such requirements (whether they are stated as a SHOULD
or a MUST) on the DNT expression.  They are orthogonal concerns that
can both be configured if the user so desires.
