This is funny because gutil.noop was never a stream, it was just a noop function.

To be honest I also was surprised by this: replacing it by an empty function caused the tests to fail. Then I noticed that it's actually calling the function: this functions returns a pass-through object stream. new PassThrough({objectMode: true}) also worked but since through2 was available I used it to match the old behavior:

https://github.com/gulpjs/gulp-util/blob/3c18e3cce5047e591ed353a8486ca1251b7f56c9/lib/noop.js#L4

module.exports = function () {
  return through.obj();
};

If I encounter it in other libraries, I'll submit a PR to document this on gulp-util's README.

Oops, I didn't realize gutil had it as a noop stream. I guess I need to update the readme and blog post.

@demurgos done! thanks for pointing that out.
