The same happened to me but I decided to renew it because my embassy told me that It would be problematic to exit the country with an expired Passport. I wasn't planning on traveling as well but I did just in case of an emergency back home, I also made sure they gave me back the old one. When you apply for citizenship they ask for your passport but I'm not sure if it matters if it's expired 

No problem not renewing it as long as you don’t need to travel before getting US citizenship.
