That's not the interesting "personality". I think the formatting tools bring in something completely different: code layouts that you would never write by hand.

I don't like that. Code should be a transparent interface, you write something and it becomes part of the program. With code formatting it becomes, you input something into the source code, you transform it with the tool, and then it's done. We sort of lose the brain-hand-program connection.

As an example I randomly found this code snippet of rust imports. To reproduce this by hand would be like writing JSON by hand - I'm referring to the nesting, bracketing and sorting. This is the lack of personality: no longer writing code by hand, but with tools.

    use core::fmt;
    use std::{
        alloc::{GlobalAlloc, System},
        cell::UnsafeCell,
        cmp,
        fmt::Write,
        marker::PhantomData,
        sync::{
            atomic::{AtomicBool, Ordering},
            Mutex,
        },
        time::Duration,
    };

    use serde::{
        de::{self, SeqAccess, Visitor},
        Deserialize, Deserializer, Serialize,
    };

"Consistency is the most important" seems to be an axiom...

"having n spaces between class methods" is definitely *not* meaningless. It affects code readability and black has very opionated (and often inappropriate) ideas about what counts as "readable" whitespace. When you raise that problem with people, they always say "well too bad, you should write shorter functions instead", which just introduces another layer of opinionatedness.
