Remove / Replace the username field with email using FOSUserBundle in Symfony2 / Symfony3

Question

I only want to have email as mode of login, I don\'t want to have username. Is it possible with symfony2/symfony3 and FOSUserbundle?

I read here http://groups.google

Instead of Validation replacing I prefer to replace RegistrationFormHandler#process, more precisely add new method processExtended(for example), which is a copy of original method, and use ut in RegistrationController. (Overriding: https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/index.md#next-steps)

Before i bind register form i set username for example 'empty':

class RegistrationFormHandler extends BaseHandler
{

    public function processExtended($confirmation = false)
    {
        $user = $this->userManager->createUser();
        $user->setUsername('empty'); //That's it!!
        $this->form->setData($user);

        if ('POST' == $this->request->getMethod()) {


            $this->form->bindRequest($this->request);

            if ($this->form->isValid()) {

                $user->setUsername($user->getEmail()); //set email as username!!!!!
                $this->onSuccess($user, $confirmation);

                /* some my own logic*/

                $this->userManager->updateUser($user);
                return true;
            }
        }

        return false;
    }
    // replace other functions if you want
}

Why? I prefer to user FOSUserBundle validation rules. Cuz if i replace Validation Group in config.yml for registration form i need to repeat validation rules for User in my own user entity.
