Unlike most IDEs, where using more of the tools means better productivity, Agile project management doesn't benefit from more features and capabilities. A memory leak finder or profiler or better lint has no downside.

Not true for project management features like, for example, "velocity" measurements denominated in story points (unitless) over time (seconds). Management metrics bullshit seldom benefits a project. In feature-monster tools like JIRA you have to do a lot of work to un-feature a project and those features are still lurking.
