It's interesting that something this minor gets people so upset. I mean, I get it, but objectively it's weird of us.

I had a debate years ago about test naming. When I was a junior, the lead dev used test methods with an underscore separating different cases. Like testServiceConnector_success(). I thought that's pretty neat and kept that style. In another project one of the devs almost had a meltdown because I dared introducing underscore scum into "his" project.
