Good! Even Windows Notepad, the extreme example of "not a code editor editor," supports \n newlines now: https://devblogs.microsoft.com/commandline/extended-eol-in-n...

Why is it good to force all your users to figure out how to set their text editors to do something different and unnecessary just because you refuse to do what essentially every other non toy language has always been able to do?
