I think the author doesn't make the distinction between *knowing* practice XYZ and effectively applying XYZ. As with anything, when we discover something new, e.g. a hammer, everything looks like nails. As a professional, I expect you to be able to argue both ways, to understand how much XYZ you need, or why XYZ has downsides and how it could hurt the company. This is not just about best practices, but about anything: libraries, programming languages, clouds, DBs etc.
