Honestly, while my cynical self would love this to be true, generating basic metrics (numbers of bugs solved, number of features added, average time a developer spends in meetings, etc.) doesn't require a lot of technical competence and already say far more than a vague metric like "velocity" (which, most of the time, is really just speed). Especially if the tool allows one to do this with a few clicks.

More likely is that, if teams were truly "self-managing", the number of management, management-lite and pseudo-management roles should be lowering drastically every year (or at least converting to hybrid roles). Yet I barely if ever see a Scrum adoption result in the majority of managers losing their jobs or changing the type of role they are performing. I also doubt data scientists would appreciate these middle-school tier statistics be called data science.
