That's just the behaviour when you run out of capacity.
Nothing prevents you from checking you're out of capacity and have
different behaviour instead.

As I said, the main advantage is avoiding dynamic memory allocations

You cannot avoid memory allocations if your queue is unbounded.

If pre-allocation of some size is a concern you can just use an adequate

For full memory management flexibility one can also build a circular buffer
