Why was this deprecated in favor of 'del'?

"Deprecated in favor of https://github.com/gulpjs/gulp/blob/master/docs/recipes/delete-files-folder.md"

const del = require('del');
var x = del([]);

x is not an event emitter and therefore 'del' is not really a straightforward replacement/stand-in for this lib, is it?

Yes I've had trouble with the recipe replacement, when the clean task not completing before other task dependency start. I've been using del 2.2 on MacOSX, which is supposed to return a promise. e.g

// clean-up dist directory
gulp.task('clean', function() {
    return del([options.distDir]);
});

Can anyone comments on this?
