I think you bring up a good point. If someone hands me a python script and told me it was 3.7 I would only hear 3 and expect it to run or fail, not to run with differing outputs!

Dot-upgrades do allow for breaking changes, but this one can break silently and I’m not sure where such breakages neither belongs in python nor where they should belong.

Personally I’m happy to get ordered ducts sooner rather than later.
