Well, most of the suggestions on here are somewhat detailed and well fleshed out, and most of the ones that aren’t come from new-ish accounts that come here and submit one or a few small suggestions. This is a (somewhat) large community, so of course there are going to be a lot of suggestions.
And if you would rather the suggestions be better written or more detailed or something (which I fully agree with) then keep in mind that all of the suggestions you have posted have been incredibly vague and simplistic 1 sentence long posts that actually contribute little to no meaningful or well thought out information.
