Please keep the previous name for consistency across versions, and allowing to be broader.

Thanks for the heads-up. This name change is already reflected in the current roadmap #73 .

In any case, we are still reviewing the approach to see if a migration script is necessary or how exactly we should handle it, whether through a direct change or by creating a migration script.

Additionally, regarding the commit order, it might be better to split it. We could first do the migration and adaptation work to version 18 relying on the connection, and then handle the name change in a separate, subsequent commit.

This way, the actual changes between versions would be much easier to track and review.
