None of these usages of `std::list` were inserting or removing elements in the middle of the structure, so there were no benefits to using it. Other uses were related to C pointers being stable in a list of strings whereas in a vector of strings, small pointer optimizations could be moved and become invalid after a modification to the hosting vector. None of these uses modified the vector after handing out a C string to an external store.
