Is it possible to have different versions of Dgraph in a cluster? In particular, is it possible to upgrade a Dgraph cluster with zero downtime by adding servers running the newer version, rebalancing the cluster, then removing the servers running the older version?

Mixing Dgraph versions in a cluster while upgrading

Are there any plans to add zero-downtime upgrades to the TODO list, if not for 2021 then for 2022? Can I request that it be added if not?
