There was a problem hiding this comment.
What would/should happen if the current cube is referenced by its name instead of CUBE here? If it fails, would the error be comprehensible enough?
I feel like it would be great to have a test for this case as well.

Also, if the error is not very comprehensible and it's not that easy to fix, it might help to leave a note on join inheritance on this page: https://cube.dev/docs/product/data-modeling/concepts/code-reusability-extending-cubes

Hi @pauldheinrichs 👋 Thanks a ton for this contribution! I'll let my team mates review this PR. And I feel like this, while not being formally a breaking change (since it was documented and there's a bug filed), is still a somewhat radical deviation from the behavior that has been part of Cube for at least a couple of years already. I believe merging this can lead to data model breakages, so it look like we should consider this for a minor, no a patch, release. Cc @paveltiunov |

#7137 - the docs specify this is supported. So adding the support for it 🤷
