I think he means "limited" as opposed to boring. The entire premise of the game is building a zoo for dinosaurs and we barely have anything to build the zoo. If they keep adding more dinosaurs they might as well just do away with all of the buildings, attractions and guests and just make it a site B game since dinosaurs are the only thing they've added at this point.
Apart from the topic at hand I will say that more types of viewing buildings would go a long way for that. JPOG had the fence mount, platform tower, balloon, viewing dome, and safari. A balloon tour and the buried dome would be a pretty big deal.
Not much else to really put in the game though considering the guests have no need to rest or go to the bathroom. The whole game basically centers around the dinosaurs.
A dino petting zoo that can have “bays” set like the greenhouse to have different tiny dinosaurs we research running around on long animation loops would be interesting to our zoo process. But it doesn’t do a ton of justice to the species that get locked in there that we couldn’t name, watch individually, feed, etc.
For that I guess we’ll have to see what the next major DLC brings
