I added some const to several API functions that take char* but typically called by passing string literals. In C++, a string literal is a const char* so you need to add a constcast<> to every call site,

That's not true.

A string literal of length N is of type const char[N+1]. However, a (deprecated) conversion of string literals to char* is provided in the language. So assigning a string literal to char* or passing it in a char* parameter is compliant with standard C++, no const_cast is required.
