Hi,

In regards to hackers it's just a myth and it was never the reason for
the Ubuntu developers decision.

In regards to user error it makes no difference, too. Assuming a user
want's to change the owner and/or group of /usr/src/ and everything
inside of this directory, an accident can happen. There's no difference
between su and sudo, running

  sudo chown --recursive 0:1000 /usr/src/

is wanted, but by accident the user is running

  sudo chown --recursive 0:1000 / usr/src/
                                 ^--unwanted space
A user who continuously would use a root console, would do it either by
su or by sudo -i.

Btw. on Arch Linux it's possible to run

 faillock --user $(id -un) --reset

by the user, IOW without root privileges. Hence after 3 incorrect sudo
password attempts there's no need to wait for security reasons. Right
now I don't have time to test it on Ubuntu.

Ralf
