As a part-time MTA developer I am not confused. The DKIM signature
provides a simple piece of trace information ("I handled this mail")
that is cryptographically bound to some header and body content.
The receiver can use this trace information for any purpose that
she deems suitable. What seems to confuse some people is that the
"using" part is entirely decoupled from the "signing" part, and
that the signer has no control over what "use" is made.
In my view, this decoupling is beneficial (DKIM as an enabler). For
others, this open-ended design is a shortcoming (batteries required).
