mab's get misinterpreted very easily, particularly because they tend to be useful in places where the non-technical (or low stats knowledge) people are the major stakeholders. Reporting on MAB functionality and output inline with other features without overcomplicating interpretation or leading to easy misinterpretation is an often underestimated task. Then allowing iteration on this without breaking any of the careful presentation or decisions made is a challenge for any MoC process.
