> CV driven development is just as well guarded against by asking someone to justify their technical decisions based on the requirements and how the solution meets them. So "boring" does nothing to further that.

It doesn't though. It's very easy to manufacture reasons why "shiny new thing" is the objectively right fit for something, even when it's not.

The word "boring" is well-chosen because it's addressing a bias most engineers have towards the interesting and new. It's a reminder: that fun new tech you really want to try here may not be, probably isn't, the cold-hearted best choice, if you're being practical and business-minded.
