This article is really good, and covers many important issues. There were many similar issues when it came to the earlier attempts to add concepts to C++ (which would improve template dispatch), although the outcome was more about improving C++ programmer's lives, not safety. It turned out trying to encapsulate all the things C++ functions, even in the standard library, as a list of concepts, was basically impossible. There are so many little corner-cases in C++ which need representing as a concept, the list of 'concepts' a function needed often ended up being longer than the function itself.
