That totally defeats the purpose of a quorum - to allow for a
distributed database without allowing conflicting changes.=20

If you allow the above, you wind up with a split network failure mode -
say your interconnect goes down, all three servers are up, but they each
think the others are down, so they decide to become sync site...
Database becomes very unhappy at that point. (Or rather, when it comes
back up.)
