Please provide documentation that the people running serious email 
platforms do not already include that factor in their decision-making.

Please provide documentation that I have said it isn't a problem.

As for changing the subject, I am indeed trying to alter it. I would to 
move its treatment in this forum from standalone, idealistic and 
apparently-uninformed statements of impractical absolutes to, instead, 
acknowledging the balancing act this is inherent in any real-world, 
imperfect analysis process of human behavior, such as email.

My usual reference to such tradeoffs is Type I vs. Type II.
