Silicon Valley (the TV show) memed about it with its tabs vs spaces bit. It used to be a thing for sure. It has been a good 10 or 15 years since I had such a discussion. Automated linting and formatting tools largely killed it in my experience.

I think the culture has just shifted. I haven't even sniffed a whiff these conversations since roughly 15 years ago. I've never, ever seen them at work.
