IMO, a lot of modern design is the result of answering the question, "how can we make this cheaper and mass produced?" instead of, "how can we make this more pleasant to use or look at?"
It goes roughly like this: the designers would always advocate for a redesign, as it is more exciting, and also because it creates more new tasks/jobs for them.
But improving things is hard, and entropy is not on our side. So, it is quite possible that the new grand redesign will be less functional than the battle-tested old one.
If we are lucky, the new design might be at least more aesthetically pleasing. [1]
[1]: Perhaps in part just because aesthetics are a function of fashion, and the new design can be up-to-date with the current trends.
