It is not just Georgia system that risk secret balloting. Think about it, in California every person had to vote by Mail or Drop Box, there are 20M registered voters and yet the in-person polling places were eliminated and only a few accesible polling places per city were provided. The Mail in-ballot envelope have your name, address and signature and a tracking number. So it could be very easy to tabulate how you voted if they wanted to. CA was challenged in court for the forced mail in vote and the court allow 'this one time' to ride. Basically said; don't do that next time.
