Even that in itself wouldn't necessarily entirely matter, nor would it address underlying issues. It would give them ideas, and maybe a core concept with which to frame the job, but what matters ultimately is how well the job actually plays in the sense of how it feels to execute job rotation, how unique and distinct it feels from other jobs, etc.,
Frankly, whether the core idea would come from one of us, or internally with the team it wouldn't matter since there's still a sort of disconnect with how it is implemented and the potential reception that it gets from the community.
Not that I disagree with you entirely in principle, as it would be cool, I just think under this set of guidelines you wouldn't necessarily address some of the bigger problems that people have or the core issues with job design in general.
