As unfortunate as it is, not every 'rework idea' thread is an actual constructive, unbiased one. More often than not, suggested reworks are based on personal struggles, and then the reworks being turnarounds and gap-filling for said struggles. But you'll still find threads that hold valuable information and actual great ideas.
But, don't take it all too serious. At the end of the day, only the devs decide what to do and how to do it, doesn't matter what suggestions they receive.
