Using undefined use statements

[w00tland]

I see omnipay-common is using some use statements to undefined classes in Omnipay\Common\Http\Client;

use Http\Client\HttpClient;
use Http\Discovery\HttpClientDiscovery;
use Http\Discovery\MessageFactoryDiscovery;
use Http\Message\RequestFactory;

There are no such files in the Http folder. Am I missing something here?

Some of those are used:

But if you want to create a PR, then that could be merged in.
