What stops folks from sticking with the last version of the last major point release? Do the flask folks not provide security or other update to older major point releases? Sometimes in the software lifecycle, you need to refactor and move on from older API designs. Even keeping old APIs around adds cruft, testable surface area you have to support, and slows down everything and adds risk with shipping software over time. Android, iOS, GTK, half the javascript and C++ libraries in the world, etc pop in into my head and all will break some amount in a major version update.
