Cool cool. >> BTW, does "unstable" cover things like dis.dis(), which have existed >> and will continue to exist for many versions, but their output can >> change?

People shouldn't be parsing that output, because it's human-readable. Does it count as an API change when the human-readable output is giving different information? Actually, I think I just talked myself out of this. The sys.version_info tuple is going to change from one version to another (obviously!), but it is, by definition, stable and dependable. So I think no, it's not "unstable" based on human-readable output.
