But that would be an API change. It is of cause a question of how strict we want to be. I have seen several times that commercial software developers denies changes bugs, as the fix would constitute API changes. We obviously do not want to go there, but we could bump the version number as it would require little work.

I would argue that it would involve bumping a minor version number, not a major version number (which indicates an API change) since it's just a bug fix.

I think we need a simpler, declarative, definition from which these details can be worked out, e.g. Same minor version: any code that worked with the old version will work with the new version, in the same way. Same major version: any code using fully explicit imports that worked with the old version will work with the new version, in the same way.
