Yes. Not because it is definitively the right answer (though it is my preference), but because a decision that's made and enforced allows the conversation to move on to other things. And to enforce it? Try https://editorconfig.org/ https://editorconfig.org/ which is supported natively by many editors (eg Visual Studio) and via plugins in others (eg VS Code). All it needs is a .editorconfig file in your folder and you get a handful of helpful settings (trim trailing whitespace, end with a newline, tabs vs spaces, ASCII vs UTF8, etc) in a simple file of rules that cascade down your folder hierarchy. Usually just add it next to your .gitignore, README.md, etc.
