As much as I want to change the behavior of the spec
I think conclusion #5 is wrong.  This mandate of not ignoring
MU headers is limited to the processing that goes on _within_
one SOAP node not to the entire message path.
On a side note, there is no way to distinguish between a valid
actor that was never hit and an invalid actor - both end up with
the same end result - it's ignored.
