I should hope so.  The purpose of that fillip (if I have identified it
correctly, from memory) was specifically to permit optimization.  Note 
that there has been some effort in committee to forbid it, because the 
commercial vendors hadn't exploited the opportunity, and (apparently) 
didn't want competition from anyone who had.

I'm happy to see that this opportunity has finally begun to be
exploited.  Go Free Software!  Now that an implementation does 
exploit it, it should be much harder to justify forbidding it.
