How do you protect against diminishing the voting board?

Suppose an organization with te Voting app has 20 voters holding an equal amount of the voting token. Suppose that during 11 years 11 members die, one every year.

Are there means to protect the organization from being unable to vote anymore in such a scenario in the existing Voting app? If no, what is planned for the future version of the Voting app to prevent such the scenario?
