Does anyone else feel that the school became much "smaller" this season?

In season 1, we were made to feel these were some of the teachers at the school, but this season it feels like the school just has these teachers (and Mr. Morton).

They all teach different grade levels so the school just feels extremely small for a public school (they do have a gymnasium but so there's probably some offscreen gym teacher). They all teach right next to each other too

Pretty much every scene in the teacher's lounge is just the main cast (and the one scene where Ms Inez is on the couch). No random other teacher that happens to work there

and it seems like Mr Johnson does the janitorial duties for the entire school
