On a desktop system, there is no valid reason for sudo to ask the user's password. Desktop users really only care about their personal files which, ironically, are the only ones *not* protected. So, basically, if you want to make a desktop user very angry, all you have to do is execute "rm -rf ~/*", which doesn't need sudo. The conclusion is that, for desktop users, asking for the sudo password protects them from nothing they really care about, and it makes their life a bit more difficult for no good reason.

OK, you set the bug invalid for sudo, so now could you please tell me which package it is supposed to affect?
