The more results there are in a category, the more points someone gets for first. This is a ranking site - points matter. Otherwise why not delete all except gold for 4700K /6700K / 7700K / 8700K submissions? 9900K is faster.
If you get hardware explicitly for the purpose of benching (this is how the Elite league is currently defined) and then don't promote it you'll lose your sponsor very quickly. What's in it for the sponsor anymore at that point?
Any chance at all to unbundle 7740X and X299 OCF? Rough load temps on your SS? I already have a 7740X so I'm trying to figure out if your chip is any better
