The problem is, to most people it just looks like you made a mistake. If you want to create breaks in your code, consider adding comments or breaking blocks out into their own functions.
Does it look like I made a mistake to most people? I've never received a comment in a PR about it and I observe other developers using the same technique, so I'm surprised to hear this, do you feel very confident in this assessment? Just trying to gather feedback here.
Maybe not a mistake, but code smell, often, yes. If you add blocks, it's usually because you want to group things together, and avoid scope leakage (if that's an issue, then you're probably doing similar things multiple times). Often a function will be a better fit here.
