Interestingly, the city of Phoenix is going in the exact opposite direction. Sometime this month (November 2019) the city is wiping out everyone's library fines. They are setting up a new system where there will be no fines for overdue books at all. If you don't return library materials after two years you will be billed for their replacement value but if you return them at that time or any time after that will get your money back. I guess they are trying to get more people to use the library system. Also, if you don't return books that are on hold for others you will get tons of email messages and then phone calls and finally you will be billed for the materials immediately if they aren't returned. If you return them later you will only get back a portion of their value based on what the city had to pay to replace them plus a service fee.
