There’s been plenty of progress. There’ve been three newer generations since the A53: the A55, then the A510, then the A520.
But what you think of as an old core design is in fact a mature, well-understood, well-tested, widely-supported, cost-effective core design. It also has some features such as in-order execution which none of the newer chips have. From an engineering perspective, it still can make a lot of sense in the right applications today.
