My experience is that if an org decides to use <HIGHLY CONFIGURABLE TOOL> then they will do it wrong the first time without external assistance. This holds true even for popular tools like Postgres, AWS, Terraform, or even Git.
Anecdotally, I don't know of any tool that is highly configurable that makes it easy for users to set it up and then scale it over time without learning the specific domain knowledge. Jira is no different in that sense. If you have an example of a tool that bucks this trend, please share it, I would love to play with it and see what I can learn about how to better serve users in this type of use case.
