------------------------------+-----------------
 When the `.editorconfig` file was added in [27198] it included the option
 to indent `*.json` files with 2 spaces, this was inherited from the jQuery
 projects `.editorconfig`

 There's no inherent reason^([#hn note])^ to require this, see

 Note: An existing issue with npm 3 and 4 causes indentation issues, as
 such `package.json` needs to remain indented with spaces until WordPress
 chooses to use npm 5 as the required minimum.
