If line breaks really were irrelevant, the author wouldn't have felt the need to give a tip all around optimising line breaks.

Personally, I would have hoped by 2026 we had better IDE's and tools for managing code in text files such that developers with different preferences for a number of characters in a column or things like how you display comments can be accommodated.
