I think this is not very good idea to MFC that into stable releases 6.x 
and 7.x. The reason is that configure scripts for some packages might 
detect up this API and enable it. Which means that some binary-only 
packages build for say 6.4 won't work on 6.3 and down. AFAIK, both 
forward and backward compatibility is required (or at least desired?) 
for stable branches.

While it's "nice-to-have" feature, I see no pressing need to MFC this
