Please learn how games are developed as well as the structure of large game studios, then please provide all-encompassing, irrefutable evidence of this because "geometry assets were there" isn't enough. How long do you think map development takes in comparison to coding all the weapons, all the systems, every quest or bounty, and then debugging and polishing it all? Not quite as long, huh? Don't you think they'd have extra time to work on some other stuff since this is a big studio we're talking about and they don't just have one team responsible for every map in both PvE and PvP? Let me also give you a little problem to solve to tell if you understand the process here; I'm gonna list two options and I want you to tell me which is better and why. Option 1 is that after they finish developing the base game map, they stop there and leave the map as is. Option 2 is that as the coding side of things gets everything in the base game put together and some side teams start work on the DLC, they try to shove as many extra map assets as possible into the file before the game goes into Alpha and Beta. As information is gotten back from the alpha and beta, they work on the main part of the map some more while possibly trying to sneak in a little bit of extra work on the stuff that isn't in the base game, leaving some of that extra stuff in the map but unfinished. I'm not going to go into specifics about what the biggest difference in execution of these two plans is, because whether or not you have the foresight to think about it from an efficiency standpoint is the purpose of this question. That's the only hint you'll get. Also, I'll just leave this out there; if you think Option 2 is better, you're supporting Bungie's decisions in making the game. Better come up with a pretty good explanation as to why Option 1 is better if you want to be stubborn about this.
