"Baggage" is used as a euphemism implying something left over from previous times usually bothersome/inconvenient ( a negative connotation ) .
By showing off aspects of the game, the gamemakers built up expectations. When the game was LATER rewritten, many of the things 'shown off' did not fit any more. Some were still included ( because of all the effort already expended on them ), but many looked 'out of place' and those things forced the game to make many story 'twists and turns' to justify their still being there.

Example : Those SteamPunky images showing the airships ('Zeppelins' are iconic ...) in the early days of the game promotionals. Zeppelins, dirigible / rigid airships in the Real World, showed themselves to be disasters and historically ineffective ( and were technologically doomed ). The Floaty technology made the game's airship shape/structure illogical and unneeded - as demonstrated by those differently designed 'Barges'. 
Comstock (and/or Fink) should have 'Future Seen' how bad dirigibles were via their 'prophesy ability', and instead jumped to something more like later airplanes ( which WON the future of air transport ).
As the game story was rewritten, they seemingly couldn't get rid of the image-recognition (iconic) 'Zeppelins' with all that promotional money they had already spent pushing that imagery. Thus, they ran with the Zeppelin on the Brain mode absurdities and the further bad Fantasy.

Other Examples :
* Choice Faked ... Everything the Player has done is thrown away ( via magic 'pinky-god' powers yet ... )
* Social Relevancy turned to Lipservice posing - a Puppetshow 'historical' backdrop
* Science and Engineering is turned to Magic Fantasy ( AND was 'Huged and Kludged' )
