It might be more convenient and appropriate to offer a choice among three options (via radio buttons):

• always to use the specific editor
• to use it only for Case elements with none-empty branches
• never to use it.

The legacy preference should then be mapped as follows: ☑️ → 🔘 always , 🔲 → 🔘 never.
The new default might be 🔘 non-empty.

More flexible and less space-consuming might be a combo-box, however.

Version hint mechanism revised (also to avoid repeated presentation of the same message):
