Ubuntu & VPN

Gotta problems trying to launch VPN in Karmic. Under Network Connections I was unable to add VPN connection. All I needed were

sudo apt-get install network-manager-pptp /
 network-manager-vpnc network-manager-openvpn

and after that restarting network modules using

sudo /etc/init.d/networking restart
restart network-manager

I`m wondering, why these packages aren`t included in Karmic by default?
