@eirnym, thanks for awesome contribution 👍

According to #235, where you've told:

Otherwise contributing could be painful
...
EditorConfig would be useful though to make editors format in more or less the same way (at least what's about the tabs and spaces)

So my question is -
Would you plz describe your reasons to delete it now?

[eirnym]

As you mentioned, it's not possible to include all formatting into this file and rustfmt won't support this file any time soon.

Additionally, even this file supports very basic rules common to every editor for Rust code, it doesn't include any rules for other file types and could potentially lead to inconsistency as root=true is present. If it wasn't present, more inconsistency could be introduced.

Thus, it's better to have either all used types included, or file is not included at all.
