Every best practice can be overused - used where not needed, used where it doesn't fit, used in trivial cases. And if you've got people who haven't developed sound engineering judgment yet, they'll start by not using those practices. But once you convince them that they should, they'll use them everywhere, even the wrong places.

This is why best practices are needed, and why they are over-rated. Where they are used, they are often over-used.
