If I'm not working towards the Twin Peak food quest, on is fine for other Twin Peak stuff. As an addendum to the tiebreaker, fine. Throw it in there.
If I'm running new AWoL and need the food/item drop from the friars to actually complete the peak, I want useful suggestions. I know I could ignore the .02% suggestions, but... if I don't need to see them, if they aren't useful, why show them? They only encourage wasting server hits, especially when running maximize from the gCLI first (wasting 3 server hits equipping +0 equipment, in addition to the hat which actually provides a +5) and then checking the tab afterwards to see which usage suggestions could push me over the top.
I see this as something similar to the 'current' keyword. For some cases, you may want to flag +current despite that it should never really be needed or provide different results. But it's good for that peace of mind.
In this case, it both allows reducing server hits as well as removing non-helpful suggestions. When that's desired. Other times, like when I'm farming in aftercore, I want those indirect options.
