Why do you want to add the useless thing of rendering dragons?

Rendering dragon makes a lot of light and shadow unusable, and it is extremely troublesome to change the package. It is said that it is to unify the rendering engine, reduce the rendering differences among platforms, and get a higher image quality experience for lower-end devices. Rendering the dragon is to destroy the light and shadow of the bedrock version, so that the lower-end equipment can get a higher image quality experience, can it destroy the previous light and shadow? I think it's just an excuse to launch official light and shadow. Low-end equipment can use low-end light and shadow before rendering dragons. If you really can't play like this, it feels worse than the agent's China version of Netease.Microsoft, you've let me down.
