Actually content like additional theme parks is not against the philosophy of the SWGemu. They are just not part of the charter for version 1.0 of this software.
For people that were part of the game when the CU hit, the problem was with the vast change in game play with the new combat system, armor certs and quest rewards that were superior to what could be crafted. I would actually say that the vast majority would like to see the Marauder, Witches of Dathomir, Secrets of the Syren and similar content added to the game.
But the project timeline is devoted to copying the game, hopefully without the bugs, as it existed with Publish 14.1.
This unfortunately means that balance issues between the professions, diversity in armor styles and other similar issues should not be a part of 1.0. These things, like additional quest content will have to wait till after 1.0 is done and may need to be done by others. The developers have talked about 1.0 coming with powerful content creation tools that will allow people who set up their own servers to create their own theme parks, or try to emulate in game content that SOE added in the way of quests, on their own.
