The point is that you never have to free a const value (free is a
specific instance of changing the value). 

Also, conveniently, I don't think we have any APIs that return a
non-const string by reference. i.e. we don't have APIs where you get a
string by reference and are allowed to modify it. 

Thus the const is a reliable indicator of whether to free, for GTK.
