With the "resolution" of this report, hundreds of user-made addons have now been broken and player's worlds are being irreparably damaged because of these poorly thought out and poorly implemented "fixes" to adhere to arbitrary performance standards. Player experience should come firsthand and if my child is crying because his chair mod has been broken by changes he's unable to understand or avoid, there's a clear issue with the direction being taken here. My other son hasn't touched the game since the last change to block geometry and I would be legitimately upset to watch another child lose interest in a game he cares so much about entirely because of a simple update. Please roll back the changes made to block geometry in 1.20.40 and consider alternatives to potential performance issues that don't involve blanket changes that break kid's realms.
Changes made in 1.20.40 seem to have exacerbated this problem and has reduced the amount of block scaling freedom to an even further degree. Mojang at this point seems to be actively looking for ways to limit mod creators and players from having fun. Oldest son quit the game when the initial changes were made and now my youngest son's world has been damaged by arbitrary block geometry ""fixes"" as well. Absurd how a game that encourages so much freedom can simultaneously deny any of it to people who want to use custom addons.
