This works until...
Specifically, until you realize that pickle changes based on python version, so updating from py3.x to py3.x+1 will prevent your application from reading previously stored data.

This is wrong. pickle can read old files just fine and lets you generate files in old pickle format versions if you require backwards compatibility further than when the current protocol was introduced (it does not get increased with each python version).
