   Actually C++ 14 proposals are intended to be either clean-up of defects in C++   
   11   
   or minor features that WG21 feels comfortable with being correct. WG21 are   
   making   
   extensive use of TS's as a way to gain experience with features that we are   
   pretty   
   sure are correct but need some field testing/experience before inclusion in an   
   IS.   
      
   'Concepts Lite' is an example of the latter; WG21 very much hopes that that TS   
   will be extensively implemented so that the feature can be confidently   
   included into C++17.   
      
   The reason that WG21 is taking this line is that the TC (technical   
   corrigendum) route used for 2003 is strictly intended for correcting defects   
   and back in the early 2000's WG21 'wasted' a good deal of time arguing about   
   whether some highly desirable    
   small features were responses to implicit defects or had to be delayed for   
   C++0x. The advantage of a fast turn round minor release is that they do not   
   have to argue about whether something is a small feature/extension or a   
   response to a (possibly    
   implicit) defect.
