Why is the folder, .mixin.out, in my .minecraft folder?

Question

I have this folder named .mixin.out in my .minecraft folder. I saw this post  on Reddit, but it lies directly in my .minecraft folder. The only things I have added recently was a datapack and a the Faithful 32x32 texture pack. Should I delete this folder? It contains a csv file which is empty and text file that says Mixin Implementation Report generated on 2021-03-20 18:02:10.

I mean you can delete it but it'll just regenerate. It's a folder created by mixins, hence the name.

Background

Mixin is a library used by other mods and/or resource packs to provide additional functionality. It's leveraged by the mods in order to hotpatch minecraft. If you View hidden files (windows) you may see more information for you to make an intelligent, informed decision as to the future of this directory, however do be aware that since this is a directory that is leveraged by mods, plugins or packs it can regenerate.
what does it hurt to keep it though?

nothing. not. a. thing.
So I can delete it?

You have to answer this yourself. You may break mods, plugins or resourcepacks. however, if you find this in a vanilla install of minecraft java edition. It's likely in use by microsoft to hotpatch some things for performance.
Google is your friend, when it comes to the content of this directory. I've purged mine with no issues, but it did regenerate when i launched my forge-powered mod.
