Might it make more sense to rather compile the editorconfig file into the respective editor's config file? That way you need not depend on a plugin being written for the editor. This would mean that you could support more editors and enhance editor configurations without having to wait for the plugin to update to support your own new features. This would be at the cost of the ease of simply editing a single file, though it could be set up that, when compiled, the system will back the old config file up and insert the new one in its place.
