As of now, I am not aware of any specifications for doing
DKIM using any other mechanism, for obtaining keys.
Defining such a mechanism will take unknown resources
and time. The output of that effort is not certain.

That's it, done.
If it's really that simple then where is the problem? If literally all we
have to do is that then there's no reason to continue arguing this point.
Is it correct that this is all that needs be done?
