I see where you are coming from, and am annoyed by trailing requires clauses in my code as well, because it wraps the brace.

Nevertheless I made this on purpose, `OwnLine` says the clause has its own line(s), the brace does not belong there.
What I refrained from, when implementing it, was another option that behaves like `OwnLine` for non trailing requires clauses, and the way you want it for trailing ones.

But that would be the way to go, add an option to the enum, don't change the existing behavior.

              It should match the bracewrapping style no?

If brace wrapping should have a saying in that, I don't know. I'd lean to: no.
