Both have this text: For more involved conversions, such as where precision or formatting need tighter control than is offered by the default behavior of lexical_cast, the conventional stringstream approach is recommended.

I've run into this problem many, many times. And hadn't realized it was possible to provide for better number conversion. In my opinion allowing such number base conversion is not only within the scope, but by not allowing the conversions it specifically imposes an artificial "tighter control" than the expected behavior.

Any chance we can change your mind about this?
