it's meant to be used within teams, with people who might not have the same editor (or the same set of plugins) as you

you just drop an .editorconfig at the root of your project and you'll know for sure that any code written by anyone will have the same indentation, encoding, and final newline config

The other useful case is when you open project on another machine for some reason and you find your usual editor not installed and configured. Open any editor and away you go with this, for those quick dirty edits. I require all editors installed to be able to read .editorconfig files and use them accordingly.

Is that widely implemented enough to be useful? Because I'm literally seeing this for the first time today.
