I am geared towards NACK here because it would be better to have this 
documented/enforced in annotations. Even with the risk that you then 
need 2 patches due to context.
Also, that is an issue but was the related bug report generated with the 
script for ADT failures? Cause in that case, once you decide this is to 
be solved on the kernel side, you should invalidate (best with a note) 
the other source which initially gets marked as affected. In this case 
autopkgtest. There was already a question about this.
