Agreed.
That's basically what happened when C++ was designed.

This could still be done in C2y, but I'm not aware of any proposals.
 

There is always going to be some hassle with things like search functions - 100% const correctness is not easy when you don't have overloads.  (It's not always easy even in C++ where you /do/ have overloads and templates.)
