There's another reason beside space for not wanting to install a port unless it's definitely needed, especially on any machine that is world facing - security. If a port is installed but unused it might aid an attacker who gets part way into a system to get further privileges. If it's not installed it definitely can't be used for that. I apply the same principle to the base system on world visible servers - if it's not used and there's a src.conf option to remove it, it gets removed.
As the old sysadmin joke goes: "Yes, I'm paranoid. But am I paranoid enough?"
