Adjacent to it are PR reviews. Suggesting simpler approach in PR almost always causes friction: work is done and tested, why redo? It also doesn't make a good promotion material: keeping landscape clear of overengineered solutions is not something management recognises as a positive contribution.
Depends on the management and whether they're involved in coding. Any engineering manager, architect, senior / lead developer etc should appreciate lower complexity. Of course, if it's the person in charge introducing said overengineering there is a problem.
Worse, to suggest a simpler approach checking existing products/APIs or even preparing toy prototype is required to be confident in own advice. This hidden work is left entirely unnoticed even by well meaning managers/engineers: they simply don't know if you knew or had to discover simpler solution.
