This looks ok but I'm curious why we are completely removing all samples for Vision Product Search?

We're currently planning on using Google Cloud Vision API Product Search with PHP, so I am also curious about this matter, what does it mean by unsupported here? does the PHP client SDK doesn't support product search or something else?
Btw, the README still has examples for the product_search.php commands, this is confusing :(.
