You missed the point.
You create *A* library that deals with *your* profile.

So, we need N libraries for N-profiles, and since the EAT document has quite
a large number of possible combinations, each use of EAT will wind up with
its own library.  There will be no reuse, which was the point of doing this work.

Yes, exactly.
It seems like it would be a SHOULD, with some exception text for some piece
of hardware that Laurence knows about.

The EAT question is what a profile should say here.
