If a node thinks it's better suited as leader, it can always force an election immediately for the next term. Things could go badly if you're wrong though
There are variants that have members than can vote but can’t lead, and I believe also ones where there are silent shareholders that are aware of part of the state of the system but don’t vote. Those would be particularly useful for autoscaling groups, where you’re not affecting the quorum count.
I think consul’s sidecar works this way but I’ve ever set it up, only used it.
