> because it doesn't matter
But, if it doesn't matter, why not let RuboCop make all `if`s consistent with `rubocop --auto-fix` and be done with it, instead of configuring RuboCop to not complain about it?
It seemed that this style choice did, in fact, matter a bit. At least enough to make you change RuboCop's defaults to accommodate to it. And that's fine; that's why those things are configurable :)
Of course, it's also fine to decide not to use RuboCop if you need to reconfigure a lot of it's defaults. Fighting with our own tools doesn't make any sense, but for some reason it's not an uncommon thing to do in this industry.
