Once I worked with a team in the anti-abuse space where the policy is that code deployments must happen over 5 days and config updates can take a few minutes. Then an engineer on the team argued that deploying new Python code doesn’t count as a code change because the CPython interpreter did not change; it didn’t even restart. And indeed given how dynamic Python is, it is totally possible to import new Python modules that did not exist when the interpreter process is launched.
