Using Bitcoin time locks for inheritance I personally think is a fascinating idea because it offers a extremely beneficial factors like security, privacy, and autonomy. But does the risk of lost access and the inability to adapt to possible future changes make it too dangerous or discouraging? Should people trust a fully automated system with something as vital as passing down wealth?
Before deciding to use the time-lock for inheritance, it has to be a decision that has been well thought out by you. You have to understand the risk and know if it is something you are willing to handle.
I don't think there is any method of transferring wealth that does not have its own risk, so it is all down to the risks that you can take and accommodate.
