Full hand count is a feature not a cost. The more people involved and see democracy happen and have actual agency in making it happen the better.

Automating any of the process is (imho) harmful to above.

I agree, but if your location has abandoned hand-counts then justifying the extra expense and extra logistics complications can be infeasible. Thus in some places it is easy to justify taking a detour through machine counts + immediate partial hand-count random sampling statistical audits designed to detect machine malfunctions with high probability.
