What I am getting at is if you don't hire devs _specifically_ who are happy working in your stack you are setting your team up for trouble. What was "I am more familiar with X" during an interview might as well turn into "We should rewrite in X" on the job, and I do feel like this situation should be explicitly filtered against in the hiring pipeline.

But then again, I am biased by having experienced the negatives of the situation.
