I would argue that innovation and trying new things are always a net positive. If you give it enough time (i.e. on a long enough timeline). Because new standards and best practices emerge. New standards and best practices that are better than the previous standards and best practices. Yes, it requires effort and debate to get to that point. But it's better than becoming stale and irrelevant, IMO.

In fact, I think a new set of best practices is already emerging in mobile app development. You just have to know where to look.
