How does this feel with Python being dynamic? I always felt very uneasy writing Python precisely because if some random module became incompatible, especially via a transitive depndency, I might not find out until it was running in production.

What's to be uneasy about? Lock your environments, pin your dependencies, especially in production.

Until your LTS OS gets to end of life and you need to switch to the next one which conveniently deprecates old python versions so you have to rewrite everything.

Why use system Python base environment for production stuff, especially knowing that it will EOL eventually and mayhem may follow? Again, pin your environments using conda, pipenv or whatever else, in which case your base Python version wouldn't matter.
