This isn’t about functionality (mostly). I did this mostly to separate the map and the vector, because the mapping will get invalidated when the vector gets sorted. If someone later on modifies the code and doesn’t know or missed the fact that the mapping is no longer valid, then they may use the MapVector incorrectly.
