ServerRequestFactory

This all works fine. Great.
But why all the logic is concentrated in one place?
Moreover, there is a class of Server.
I think it would be better to make a directory of the factories.
Firstly, it allows to separate each logic element in its factory.
Secondly, because I can always get in the code of the original values.
For example, Zend\Diactoros\Factory\HttpProtocolFactory:

use UnexpectedValueException;

class HttpProtocolFactory
{
    public static function make(array $server = null)
    {
        if (empty($server)) {
            $server = $_SERVER;
        }

        if (! isset($server['SERVER_PROTOCOL'])) {
            return '1.1';
        }

        $protocol = $server['SERVER_PROTOCOL'];

        if (! preg_match('#\A(?:HTTP/)?(?P<version>\d{1}\.\d+)\Z#', $protocol, $matches)) {
            throw new UnexpectedValueException(sprintf(
                'Unrecognized protocol version "%s".',
                $server['SERVER_PROTOCOL']
            ));
        }

        return $matches['version'];
    }
}

All this is true for the request method, headers, Uri, uploaded files etc

And for the host is must be required!
forced host... This is not such a rare situation. And it should be done without interfering with the application logic, the best from the index.php

use DomainException;

class ServerHostFactory
{
    protected static $forcedHost = '';

    public static function setForcedHost($host)
    {
        static::$forcedHost = $host;
    }

    public static function getForcedHost()
    {
        return static::$forcedHost;
    }

    public static function make(array $server = null)
    {
        if (! empty(static::$forcedHost)) {
            return static::$forcedHost;
        }

        return static::calculate($server);
    }

    public static function calculate(array $server = null)
    {
        if (empty($server)) {
            $server = $_SERVER;
        }

        // from server config, if present
        if (isset($server['SERVER_NAME'])) {
            return $server['SERVER_NAME'];
        }

        // from headers, dangerous to use
       /* if (isset($server['HTTP_HOST'])) {
            return $server['HTTP_HOST'];
        }*/

        throw new DomainException(
            'Missing host in server parameters.'
        );
    }
}
