Software that's not getting any attention will be ok as it won't get python upgrades. Software that is getting attention has a nice long warning period and fixes may not even cause any trouble at all if the code is ok and there are unit tests. New software won't have a whole class of timezone problems because people will use the better API to remove the warnings. I cannot see what the big problem is - much more troublesome things happen in Go all the time. Python isn't a huge for-profit company like Google or even MS which has to dedicate efforts to ensuring that games from 1992 still run in 2023.
