I don't exactly like this. If one application gets compromised, it can now 
open other ports that may be protected. Previously, it would require 
CAP_NET_ADMIN or some other root possessed capability to make changes. There 
are a lot of important services above 1024 that a normal user could bind to. 
You don't want the system to suddenly open those ports and allow traffic.

This part I like.
