>I think I made the original posting more with the objective of light relief in challenging the conventional wisdom, but with some view to saving yet another field entry which a lot of computer users make many times per day. I don't think for one moment that things will change. Maybe it could be a good practice for the application to fill in the user name automatically which would then save that second field entry. What would be wrong with that ?

If I understand you correctly, you are suggesting having a user name and a password field on the login screen, but the user name field would be defaulted to the current user that is logged into the OS. Is this right? If so, I think this is a good idea.
