This is a 00s POV. If you spend any time on syntax formatting in 2026, you're wasting it. It's a solved problem.

Any reasonable language with braces has standard formatter that will just put each brace level on a different whitespace level.

Working in C# i feel basically still read code structure by the visual block structure / indentation. I dont think I've ever counted braces in my professional life. The IDE makes sure it is formatted correctly and ambiguity is basically impossible.

Nevertheless it happens that while moving code around one wonders what indentation level that code should go. Undo, undo or git show the original code, look at it, retry more carefully.

Brackets would allow the editor to autoindent the pasted code.

No choice is perfect.
