Also not sure whether it is an implementation detail or the behavior that should always be anticipated.
People build performance sensitive code assuming the cost of certain operations -- like, assuming that erasing elements from a vector never reallocates it; and that the only operation that sheds capacity is squeeze(), everything else (incl. clear(), incl. resize(0)) keeps the capacity (*). We should stop backstabbing them...
(*) Which of course opens an interesting discussion in case of these operations detach
