Custom Launchwrapper Arguments for JSON Patches

[uniformization]

Role

I’m adding custom Launchwrapper arguments to Mixin.

Suggestion

I want to be able to put custom Launchwrapper arguments within my JSON patch file.

Benefit

I will be able to load mixin configurations through Launchwrapper easily.

This suggestion is unique

You may use the editor below to elaborate further.

Currently, I can already add my own Launchwrapper arguments by adding it to the +tweakers array. This method is a bit unusual and I would prefer to use another array to put my custom arguments in. I suggest something like +lwargs where people can add their own arguments in.
