Indeed. QList causes confusion for the uninitiated that are aware of
the differences between std::vector and std::list
(as in Why Do These People Use Lists Everywhere? Why don't they use
Vectors?). Now we have papered over
the problem, but the name remains problematic, because QList is not a
list. In Qt5, QList is sometimes a list,
sometimes a vector, but in Qt6 it's never a list.

Switching the QVector implementation over to a type called QList and
aliasing QVector to that with the intent
of getting rid of the QVector name seems exactly backwards to me. I
would think the better approach would
be to keep dev as it is, and deprecate and eventually remove QList.
