I think the patch is worthwhile, even without this additional optimization. In fact, If the optimization was part of
thepatch, there would probably be calls to factor it out, on the ground that the patch is already rather large. 

I don't see what bumping the whole thing to 9.5 buys, compared do applying what we have now, and optimizing in 9.5
further.
