So my argument is against

* `ZfcUser\Form\LoginForm`
* `ZfcUser\Factory\Form\LoginFormFactory`
* `ZfcUser\InputFilter\ChangeEmailFilter`
* `ZfcUser\Factory\InputFilter\ChangeEmailFilterFactory`

and for

* `ZfcUser\Form\Login`
* `ZfcUser\Form\LoginFactory`
* `ZfcUser\InputFilter\ChangeEmail`
* `ZfcUser\InputFilter\ChangeEmailFactory`

or, if you really need to have factories in a dedicated namespace:

* `ZfcUser\Form\Login`
* `ZfcUser\Factory\Form\Login`
* `ZfcUser\InputFilter\ChangeEmail`
* `ZfcUser\Factory\InputFilter\ChangeEmail`
