It's true that it creates an overhead for maintainers. But, on the other hand, maybe Linux process needs to be improved to relief the maintainers from having to review every single patch.
Linux as a project is big enough, and if maintainers are the bottleneck, maybe it's time to have sub-maintainers to whom such tasks could be delegated.
