I don't remember, sorry. I'm not sure we actually ever discussed that aspect, we spent far more time discussing the content of the NTBS it prints.
Personally, I don't think this should really have been handled as a library issue. It's more of a new feature, like [Printing `volatile` Pointers](https://wg21.link/p1147r1). And since I'm not aware of anybody actually caring about this feature, I haven't spent much time thinking/caring about it.
If users were requesting it in C++11 and C++14 modes I'd consider enabling it, but I don't think anybody has asked for that.
