zendframework/zend-http 包需要49个组件正常吗？

Question

这是composer.json：

{
    "repositories": [
        {
            "type": "composer",
            "url": "https://packages.zendframework.com/"
        }
    ],
    "require": {
        "zendframework/zend-http": "2.*"
    }
}

...以及详尽的清单：

Authentication  Code     Db     Escaper       Filter  InputFilter  Log     Mime           Paginator    Server          Stdlib  Uri        XmlRpc
Barcode         Config   Debug  EventManager  Form    Json         Mail    ModuleManager  Permissions  ServiceManager  Tag     Validator
Cache           Console  Di     Feed          Http    Ldap         Math    Mvc            ProgressBar  Session         Test    Version
Captcha         Crypt    Dom    File          I18n    Loader       Memory  Navigation     Serializer   Soap            Text    View

其中一些实际上是有道理的。但是例如Barcode,Captcha,Navigation 甚至Db呢？
