I concur with the misuse of the word "slop". But this is almost exactly how i setup my browser anyway and since I only do that on once i am nor sure how useful this is actually... maybe for setting up systems for others?
Multiple machines, multiple instances or profiles
Yeah, I was gonna say. These are reasonable defaults for a technical user and I do much of the same, but it's also reasonable for many users to want the features that are being disabled here. It's not slop just because the author personally does not want them.
I find it most useful for a shared family computer with multiple users, but I also appreciate any type of config-as-code where possible
