Why do we need to mention GPU?

I can see this can help some, users, but it also can misleads other users who has issue, but not GPU libraries.
If we can detect The Library, then maybe there is a value in the message.

What is % of total issues do we expect caused by GPU libraries? 
We need a confidence that it's high to blame them.
