I left one company 3 years ago in the middle of a major transition between versions. The "right way" changed fairly drastically, and surprise surprise, they're still stuck in the middle of that transition.
I think this is largely why I have found myself preferring static typing with roll-your-own framework style / library-based ecosystems over batteries-included systems.
When your language or framework of choice suddenly insists that you use AA batteries instead of button cells, and it is up to you to modify every electronic device in your house to use them, it gets real old real fast (an exaggerated example, but not entirely unheard of).
Really should be, write stuff and test it locally on my machine, put it in a container and upload it. I know Lambda supports containers but sometimes I feel like its too much of an overhead, especially with shitty upload speeds but I really don't see any other choice unless I manually build AWS Lambda layers myself.
We've come a long way since PEP 20.
