Aggressive IDE-supported semi-automated refactoring has replaced UML. Modern languages have been designed with toolability in mind. Modern IDEs allow ruthless redesign of the architecture of code on the fly, allowing architecture to be modified to reflect actual need rather being a fairytale written before the first line of code gets written. Teams aren't shunning design. They're just doing it incrementally, because as it turns out, trying to design a piece of software before the first line of code is written doesn't actually work. Even in peak UML (2000 or so) there were no really practical UML diagramming tools. (Rational Rose was impractically expensive, and buggy enough that it was a race to see if it wouldn't crash before you actually finished your diagram). Corel Draw had passable UML diagraming support. But I don't imagine it still does.
