My suggestion is that server owners/admins should be able to use a command to ignore normal power requirements and damage calculations. The reason being that it can be used to make AI enemies harder and indestructable areas.
Currently all AI enemies are limited by the same power requirements that players have so a server owner can use these commands to make better PVE enemies, for example if you have a borg PC faction (once custom PC controlled factions are added) you can place an Invulnerable tag on the core of their main base area so that while it can be seen and shot at players will never be able to destroy it, and then you can use commands to greatly increase the power of their weapons so that they feel more formidable because normally a player would kill them by just making a bigger ship. Thus if you wanted you can have the Reapers from mass effect as enemies and give them better shields and guns despite the unsual shape of their ships.
For planets if you wanted to have a planet be the starting point for new players you could put turrets and increase the range so that you could if you wish protect players from being stalked when they enter the outer area. Or in combination with a message system warn them that once they leave the beginning zone they cant go back.
And finally if you had somesort of server activity you could use the Stat modification to make special ships for an event or any kind of PVE game.
