a Last Will option.
A way to leave a note for friends and family ... just in case.
And of course, a way to give a person of my choice full access to my 1Password DB after I'm gone.
The big issues are, of corse security, security, and security.
How do you know I've passed, and how can you verify my 'person of choice'.
I do have a suggestion in that regard. CHARGE the 'person of choice' a (reasonable) fee. That will minimize some of the potential fraud.
PS. Before you ask, I love my family. But I'm not sharing my passwords while I'm alive
