Coding Style Comprehensibility introduced by
$return was never initialized. Although not strictly required by PHP, it is generally a good practice to add $return = array(); before regardless.

Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code.

Let’s take a look at an example:

foreach ($collection as $item) {
    $myArray['foo'] = $item->getFoo();

    if ($item->hasBar()) {
        $myArray['bar'] = $item->getBar();
    }

    // do something with $myArray
}

As you can see in this example, the array $myArray is initialized the first time when the foreach loop is entered. You can also see that the value of the bar key is only written conditionally; thus, its value might result from a previous iteration.

This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization $myArray = array() either outside or inside the foreach loop.

Coding Style Compatibility introduced by
The method admin_page_load() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

6721
	 * all the files into one file.
6722
	 *
6723
	 * Pros:
6724
	 * - Uses only ONE css asset connection instead of 15
6725
	 * - Saves a minimum of 56k
6726
	 * - Reduces server load
6727
	 * - Reduces time to first painted byte
6728
	 *
6729
	 * Cons:
6730
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6731
	 *		should not cause any issues with themes.
6732
	 * - Plugins/themes dequeuing styles no longer do anything. See
6733
	 *		jetpack_implode_frontend_css filter for a workaround
6734
	 *
6735
	 * For some situations developers may wish to disable css imploding and
6736
	 * instead operate in legacy mode where each file loads seperately and
6737
