It makes it easier to debug and figure out what's going on behind the scene.

When using this syntax:
-device DEVICE,netdev=ID -netdev socket,id=ID,udp=LHOST:LPORT,localaddr=RHOST:RPORT

Before:

(qemu) info network
Devices not on any VLAN:
  rtl8139.0: type=nic,model=rtl8139,macaddr=00:ab:29:8c:3e:00
   \ gns3-0: type=socket,socket: udp=127.0.0.1:20003
  rtl8139.1: type=nic,model=rtl8139,macaddr=00:ab:29:8c:3e:01
   \ gns3-1: type=socket,socket: udp=127.0.0.1:20002

After:

(qemu) info network
Devices not on any VLAN:
  rtl8139.0: type=nic,model=rtl8139,macaddr=00:ab:29:8c:3e:00
   \ gns3-0: type=socket,socket: udp=127.0.0.1:20003, localaddr=127.0.0.1,20004
  rtl8139.1: type=nic,model=rtl8139,macaddr=00:ab:29:8c:3e:01
   \ gns3-1: type=socket,socket: udp=127.0.0.1:20002, localaddr=127.0.0.1,10000
