Can you undo the commit removing curly braces? I like using them. I also don't think users should change the code style except in dedicated PRs.

Yes, done.
Code coverage dropped a little though. But couldn't find any uncovered parts in the code I wrote. So I did this one: 05c2a4c
Not logically related to the PR either, although an improvement I'd say. I can do it on another PR or remove it altogether. Let me know what you want.

Ah, I see now that the project coverage has improved, but patch coverage has decreased. 🤔 Don't think i understand.
