I think the importance of the setter isn't as interesting until V3/V4 and above. V0 is a ladder with a couple missing rungs, no one's forgetting how to set those. I also don't think there's pressure to be a "hard" setter, it's just very challenging to set really interesting routes in harder grades that are accomplishable and don't have loopholes/workarounds. If anything the pressure is to be really creative and challenging at any grade (realistically above V2 or so).
