While the only people who can answer that with any authority are the people 
providing the closed source drivers, there's no fundamental reason why EXA 
would be any harder to use within a closed driver (that I know of).

As a practical matter, nvidia's closed driver already implements an 
acceleration architecture internally that's superior to XAA, so I doubt they 
would switch to EXA unless it provided some measurable benefit.  As far as I 
know, all the other closed drivers use XAA rather than rolling their own.
