The proposal is that we only need to provide the string_view overloads. However, string_view strings are not guaranteed to be null-terminated. This means that an implementation that uses inet_ntop and inet_pton needs to copy the string to a temporary buffer first. By providing the const char* overloads we give the user an option for avoiding this copy.

In Cologne, Jonathan Wakely indicated that he would probably want to provide the additional const char* overloads anyway, but it's not clear to me if this is permitted.
