I'm not sure how to interpret this statement. I think what Alex is
saying is simply that patches should include some justification. They
make changes but what are they improving?
For example:

        I tested device ABC in conditions DEF. Without a patch VM
        stops. With the patches applied VM recovers and proceeds to
        use the device normally.

is one reasonable justification imho.
