If their population gets to big dont they just split essentially, the old queen and a bunch of bees "swarm" which is just them moving elsewhere, which the old hive usually just raises a new queen and keeps going.

Or are you saying they are worried to many bees will leave or they may not get a new queen in time?

What I was talking about is taking honey from bees. You take too much some of them will die, you don't take any the population will grow. Beekeepers know how much honey to take so they won't breed too much and split (because you bees expanding and splitting doesn't benefit you).
