Because with std::vector it has been possible for the last 16 years (by
using a custom allocator), _and_ this behaviour has been well-defined by
a Standard (unlike QVector, whose behaviour has always been undocumented
/ implementation defined, and possibly changed between Qt 3/4/5 and
maybe will change again in Qt 6).
