It depends on what you mean by default and whose default.

You can change your own defaults quite easily!

Changing the default setup with emacs that has been shipping for > 30 years is tough.

Getting nginx to ignore a well established pattern by a well established editor seems equally sensible and perhaps more doable. Yes?

By default I mean whatever you get by doing `sudo apt-get install emacs-nox`

I disagree about "tough". Emacs has changed for the better in new releases quite drastically in the last years in my experience.
