This is not just a Python problem. I remember when PHP shifted from 5.6 to 7 - I used many projects and software which needed to be updated because e.g. all the mysql_ functions and some crypto functions were removed. Same Issue with e.g. converting Vue 2 to Vue 3 or Angular.js (Version 1) and Angular (Version 2). I really hate when some programming languages or frameworks completely remove important functions which were used by nearly every project.
