Any reason the setProperty method allows empty arrays?

Hi!

Love the package, use it all the time!

Quick question about the setProperty method. Any reason this method allows empty arrays? E.g. would be nice if the following would not add a property to my Organization object:

Schema::organization()
    ->name('Company')
    ->image([]); // The empty array is a result of a array_map() expression

This results in:

<script type="application/ld+json">{
    "@context": "https://schema.org",
    "@type": "Organization",
    "name": "Company",
    "image": []
}</script>

Seems to validate just fine:
