One place I worked wanted multiple people to "own" a story, but JIRA doesn't work like that, so they implemented a totally new custom "owner" field that did allow it and then told everyone not to use the native owner field. Now you had to track everything two ways.
What makes this worse is when 1/3 of the teams in your org decide that they want a similar feature, but each comes up with their own custom-named tag ("owner", "lead", "point person", "point of contact", "jefe").
And then you want to run some jql queries against those tickets, and you have to use disgusting query generators to de-dupe the tag monstrosity.
They've done an excellent job of giving you just enough features to shoot yourself in the foot with.
