Hi @kaznovac,
To some extent, this is already possible using the http_handler client configuration option. You can use this to specify your http implementation, but you are bound to having it return a guzzle promise containing a class that implements Psr\Http\Message\ResponseInterface as the response.

With a bit of custom code, this should work for you if you're only looking to have control over the client. If you're looking to decouple from guzzle all together, then this would need a major version bump to change it. Is setting http_handler sufficient for your use case?

Thank you for the quick answer @SamRamis :)

I'll investigate the suggestion.

In the future, I believe, it would be beneficial to the library to decouple it from the concrete http client.

It would be great if this package in a future version depends on php-http/discovery instead of guzzlehttp/guzzle and guzzlehttp/psr7. (More on this package on https://docs.php-http.org/en/latest/discovery.html)

This would require updating the minimum PHP version to 7.1, but with a user base of less than 1% of composer users on older PHP versions, that should not be a problem.
