Just a random sample from my home directory right now on a random dev server: .ssh, .gnupg, .vscode-server, .zshrc, .ipython, snap, .antigen, .pki, .profile, .python_history, and there's much more.
I don't know what's the situation with desktop linux, may it's better, maybe it's worse, but even on a headless dev server it's already a lost cause. Trying to convince everybody to move to a new standard is a hopeless task, imo, best to move on.
