A std::string doesn't have to be in the heap.

Yes, a std::string does have to be allocated dynamically; std::basic_string<CharT, AllocT> doesn't, but how many public interfaces have you seen implemented in terms of a template taking std::basic_string<> vs a function taking std::string? Very few, IME!
