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.
I also never have these conversations at work…because every repo uses a linter and the engineers are mature enough to recognize most of these debates as bikeshedding. Every once in a while someone will suggest turning on or enabling a new custom rule with some justification and there is a brief discussion and it is enabled or not. Outside of work in a consulting gig I didn’t have a linter in the codebase and the owner brought on a new engineer, he wrote if else statements all on one line no matter how long they were and removed spaces everywhere because he thought shorter code was better. He balked hard at any feedback about code style and I was told I couldn’t enforce code style or install a linter. I think you will surprised how much you care if someone with a truly weird style starts putting it in your codebase, I always told myself I didn’t before this. After more dumb waste of time clashes like that I quit the project. Now even personal projects get a linter :).
