The reason to keep it as deprecated is so that those customers who don't want to do a huge amount of search-replace immediately can get things working again temporarily using -Wno-deprecated. It provides a simple temporary fallback cushion, and then we can completely remove the function later. 
So, I'd like to see us remove all our usage of the function internally in 1.7, along with marking as deprecated, and then completely remove in 1.8, (i.e. in a week's time or so) :-)
