While i agree that in general authors should not add roles to elements that
have implied default roles,(although this does no harm, it is a waste of time)
there are some cases that this is legitimate and therefore should not be
forbidden:
in cases where default roles have not been implemented in browsers and no
timeline for implementation has been provided and adding the role actually
helps users as they are recognised by AT.
for example the article element.
In cases where a developer wants to use a non global aria attribute that
applies to particular role, they are required to add the role (as this is what
implementaions require)
example 
<button role=button aria-pressed=true | false>

If it is agreed, then a complete list of legitimate exceptions can be provided.
