As you continue to update through 1.15, 1.16 and it seems like beyond, you're continuing to kill the game and do everything the community is asking you not to do. Stop making render changes that make mods like Optifine impossible to maintain, you're not helping anything. Care a little more about performance, care a little more about server performance. It will go a long way. In-House features, specifically relating to entities and performance is atrocious and requires the community to make mods, plugins, and custom server jars to remedy the carelessness. Please take a step back and talk to the community. Meet with the developers, meet with the mod developers. Java is not dead. Java is growing.

What are you thinking? First of all, this is BUGS.mojang.com. There is the MINECON every year and players have 3 options to vote for. There is a feedback page where you can give your ideas and other players can vote for it. It is also very common that Mojang asks for feedback before releasing a new feature in a snapshot, or removes it when there is negative feedback.
Minecraft doesn't work together with Optifine. Of course Minecraft makes render changes in order to improve the game.
The performance issues in the latest snapshot, I mean, who cares? It is a SNAPSHOT. Full versions work fine most of the time.
Minecraft will ever release new entities, items, feature, performance upgrades. That is called development, I really don't know what you are thinking. 'Meet with the developers', that is the best part.
Bug tracker is not the place for feedback
