I think it's one of those "can't please everyone" things. For years people have complained that they don't want moderators to access the CP.
As a consultant, I probably did the same number of jobs removing the admin panel from mods under 6.4 and earlier as I do applying the mod to add admin access back for mods under 6.5.
Ideally this would have been admin configurable as to who could see the admin panel.
