Oh I think indentation helps a ton with readability. Even for bad, long or otherwise hard to read code - it would be way, way worst with no or wrong indentation. Correct indentation helps a lot. It is not the only thing that can be done to improve readability but it is the first and simplest fix you can apply to a code base. So a language enforcing it with syntax does not matter when even basic text editors can correctly and automatically indent your code.

Though one thing I do like about bracers is I can be lazy with formatting and let my formatter sort it out for me on save. With a white space sensitive language you need to get it correct from the start or else the program just does the wrong thing.
