Code style discussions

[PrinsFrank]

This came up in a comment: #425 (comment). The PR has since been merged, but It's good to make this repository as easy to contribute to as possible, so it makes sense to start a discussion here. PHPCSFixer is configured to use PER3 (which replaces PSR12), but there are many custom settings added that reflect the way I'm usually writing code. I'm open to evolving these standards if it helps contributors. What would help here?

I would prefer a line length limit of 120 characters as defined in PSR12 and PER3 as I find it forces you to format complex code in a more readable way. But ultimately it does not matter to me. Your project your rules.
