Public voting is not status quo outside of Debian. In the real world the only places that have public voting are places that are controlled by dictators.
Most (all?) US legislatures don't have private voting and are not controlled by dictators; not sure about other countries. Voice voting does happen in some contexts and doesn't leave a record of who voted how, but most contested votes are recorded.
To me, Debian Developer feels more like a position of responsibility and representation than a member of the public. But I'm not one, and I don't know what the expectations are.
I do think ranked choice voting is dumb and adds low value and high complexity. This thread with hundreds of comments affirms that notion.
