It could have required a version of filebuf::open() (or similar) taking
a FILE*, given that <cstdio> is part of the standard. 

And, realistically, most of the machinery is likely to be in place in
order to implement cin/cout/cerr/clog. Given the existence of
ios::sync_with_stdio(), it seems like it would be quite hard to implement
this in a way that didn't facilitate creating some kind of streambuf from
a FILE*.
