Hi @remie , @marc , @ademoss , @ernst.stefan and @james.dellow ,
Thanks for pointing out these concerns. I’ve had a chat with the Confluence Cloud team and my understanding is that they thought there would be no impact on apps. We discussed the questions you posed and how impact can occur even when there are no formal/obvious API changes†.
The Confluence Cloud team now intend to research how this feature may impact apps, including the areas you have highlighted above. Once that research is complete, the team will be in a position to communicate this in the Confluence Cloud changelog. The team won’t make any changes resulting in impact without sufficient notice through the changelog.
Regards,
Dugald
† Note that I have been maintaining a classification of API changes and this change prompted me to add a new type which I’ve labelled cardinality. You can see the definition here.
