40 votes isn't so much. As part of a deep curation team, I'm probably least likely to misestimate the situation. Daily, there are approximately 3000-4000 shit posts, 200-500 posts worth a read. 50-100 are very good - well worthy of upvotes. About 10 are excellent. 5 is nowhere near enough - at that point all curation on the site will grind to a halt.

If you read the comments, pretty much every regular curator is opposing this proposal for this very reason. For me, it's clear there are 50-100 posts every day that deserve my upvotes. With a 40 votes/day target, it's possible to vote on all with voting weight control. With 5, curation - in the true sense of the word - will halt on Steemit.
