100% this is a huge flaw in our industry, it applies at the highest level (CTO, architect) too. In a friend's company, their CTO has mandated a rewrite of the backend in Clojure, and that it should be as asynchronous as possible. Low and behold, the devs aren't familiar with the language, and the async has resulted in a host of heisenbugs, that are hard to reproduce. On the CTOs resume though, he would show how he got the shiny new architecture rewrite, any problems were the devs fault.
