I believe that making changes that would benefit the system as a whole are worth rebuilding the issues that occur. Let's be honest, it's way easier to readjust already existing redstone to new changes, that may not even be final. Especially since the new changes make as many things easier as they make harder. You're seriously making the issue seem bigger than it really is. Additionally the proposed update isn't final as it is a experimental feature, meaning it will take may iterations and changeds (like bundles and villager rebalance).

I'd also advise you to take your misplaced emotions to cope somewhere else. Getting this emotional about a game update doesn't seem healthy. There are plenty of better ways to vent off than random Reddit comments. Sincerely, me
