I am not sure how it is insecure, could you elaborate? At least to me
giving (limited/full) root privileges to an ordinary user seems a lot
more risky.

The way I understand it if I have the following in my /etc/sudoers
file,

%<user_group>  ALL=(ALL)       ALL

then there is no difference (other than the logging) between how the
command is executed as compared to,

$ su -
Password:
# <command>

If my understanding is correct, I fail to see the source of the
insecurity.
