Good. (At the risk of stating the obvious: Changing commonly established things is how progress works.)
I'm not sure how big the gain is here. Are people really going to read "man in the middle" and assume that no woman could ever do this?
Why is it good? What benefit does it achieve other than confusing people. It is also a good reminder that how things were before. One should not forget the past and things accomplished by many efforts. How is it different than 1984's newspeak or the idea of 'changing the history? Why not choose an approach similar to this (first link I found about Warner Bros' approach): https://twitter.com/stilkov/status/506324544177836032
