Getting the same output on Python 3.7 and Python 3.8 is also matter for https://reproducible-builds.org/
If you want reproducible output, you should settle on a well-known version of Python. You don't expect two different versions of gcc to produce the exact same binary. Even compression utilities (such as gzip, xz...) can get improvements over time that change the binary output, for example making it smaller.
