It's become irrelevant because technology is now the measure of all things. It's an outdated mindset to view science and the pursuit of knowledge as sacred things that must have an order. If the technology is progressing, then the field is, therefore there is no need to care about the abstract concept of "progress of science", as it is tangential in practice.
I think many comments are missing the point though, people care about Kuhn because of his epistemological innovation and the implications of his work on the very idea of science, not because of its reception by science historians, however great it may have been.
