I bet Stoutland would be close to useless without Superpower, Wild Charge, Fire / Ice Fang, and Pursuit. Stoutland is effective because it has an usable Attack stat with very good coverage; since in the threat discussion it was agreed upon (I think) to not give it much coverage, your example is not overly convincing to me. We can tune the stats of CAP5 to reduce the Hidden Power viability on it quite easily, if we don't want it to be able to deal with walls. This is not really aimed to counter your argument, but are we really willing to give CAP a 115 Speed stat, Pursuit, and Rapid Spin? Looks really a perfect Spinning machine to me...that even ignoring the ability it's very attractive for every team based around SR removal (not necessarily Sun). I would think twice before using weird stat arrays just to grant CAP5 the ability to run LumRest, since we could end up breaking other aspects of the pokemon that have seen a lower amount of discussion. This is not against Harvest, just I'd be more careful before proposing or even considering an unconditional base 115 Spe in your examples.
