I am surprised by this because Python minor versions break backwards compatibility all the time. Our company for example is doing a painful upgrade from py39 to py311
Could you explain what major pain points you've encountered? I can't think of any common breakages cited in 3.10 or 3.11 offhand. 3.12 had a lot more standard library removals, and the `match` statement introduced in 3.10 uses a soft keyword and won't break code that uses `match` as an identifier.
