And not only for security reasons; If you have time have a look at http://bugs.archlinux.org/task/14926 in that case the permission problems affected the system directories.

And times ago there where permission (umask) issues with users calling pacman with sudo.

There is no problem calling pacman with sudo, I do that all the time. I think what you are referring to was a problem with non-standard umask, which has been fixed in pacman : http://bugs.archlinux.org/task/12263 If you used pacman as root with non-standard umask, you would have had exactly the same problem.
