The "we use the right tool for the right job" mindset looks good on paper but doesn't scale very well.

Most of the time it tends to favor developers who are the most distracted by the newest and shiniest trends.

It is helpful for any dev team to have 2 or 3 programming languages in their toolbox that they can use to solve their problems. Any discussion about adding a new language to that toolbox would need to involve discussions about QA, deployment and long-term supportability. Unfortunately most developers are less concerned about those "non-technical" aspects.
