We do currently have an abandoned tool in our chain that was built about 4 years ago but the guy ran away. We have yet to untangle his mess. Our operations/devops units kicks heavily against stuff like this for this very reason.

Unless I can guarantee myself (and them) that my tool will be a very tight integration with the rest of the system and not become a wart, then I rather won't introduce it. It has to fit properly with the rest of the puzzle.
