weight reduction

I have thought of a new feature for Minecraft!
I'm using a translation tool, so please forgive me if my English is a bit strange!
The new feature we've come up with is called "Lightweighting".
This new feature is to have a new lightweighting setting in the settings section!
I've been thinking about the pros and cons myself.
The pros include less lag when using the preview of the delay technology, faster loading of textures, and less stress for the player!
When playing Minecraft on my phone or Switch, there is lag and sometimes crashes when playing with add-ons!
I came up with this idea to alleviate that.
Next, the cons.
The cons are more bugs, more admin work, and less need for lightweight mods like Optifine.
Still, I would like to see it added.
Because it is not possible to install lightweight mods in the integrated version.
Thanks for your consideration!
