This is absolutely something that you should fill out a support ticket for an answer from staff. If it deals with anything regarding the rules, it should be asked via the ticket system so staff can give you the most accurate answer!
If you (or anyone else!) have specific ideas for how Subeta should treat end of life wishes, digital wills, or anything along these lines, please post your suggestions in the Suggestions & Ideas forum - that's a better place for suggestions than this forum.
