The converse transform would be trivial (it’s always safe to use a std::string instead of a StringRef, you’re just going to end up with lots of redundant copies), but going in this direction requires reasoning about the surrounding code.

The idea is to go from std::string to StringRef/Twine, not the other
way around, so the problems are usually non-trivial.
