The fact that all our code would break if we changed it? :-)

Well, seriously, the answer is that none of us are maintaining STL,
we are just using SGI's version -- so I suppose the question should
go to the SGI STL folks asking why *they* haven't fixed this.
There would probably need to be some kind of backward compatibility
flag.
