Why not? Maybe I have a lot of monitors and want to dedicate a small one to a taskbar where I see the full pathname of each editor that has a file open. People who just randomly click things without even realizing they're clicking may just as well delete random files or worse, the taskbar taking up half the screen is about the most harmless consequence I can think of. If it's really such a worry, add a dialog that asks the user "are you sure you want this?" for anything "weird", with a checkbox to "never ask again". If people "accidentally" click that, too, that is really their problem.
