Why Irules add Server Header in HTTP::respond and HTTP::redirect

As observed when ever I use HTTP::respond or HTTP::redirect for 302, LTM add server header in response i.e Server: BigIP. Is this a standard behavior and could this be changed. For Example Irule is....

I believe it's there to make the troubleshooting easier and it might even be a standard since other web servers does this as well (IIS, Apache, Tomcat etc) You can probably remove it in the HTTP_RESPONSE event.

Untested iRule: 

when HTTP_REQUEST {
    HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
}


when HTTP_RESPONSE {

    if { [HTTP::is_redirect] && [HTTP::header value "Server"] == "BigIP" } {
        HTTP::header remove Server
    }

}
