Yes, which would actually lead to them either needing to rectify it, or they would collapse and let other realms destroy them or remove land they can not feed, or sacrifice them to rogue. That is in my opinion preferable to a constant cycle of JUST scrapping by and doing nothing else.
With seasons, if you're in trouble you're only in trouble for a short time, then you have three months where you can direct your attention somewhere else and attempt to rectify the problem before it reoccurs.
Without seasons, you can't do that. Your realm is collapsing right now, and it won't give you a breather. You don't have time to go declare a war to grab more rural regions and bring them up to shape so they produce enough food to feed your city - it will have starved before that.
