Interesting.
However I fail to see how it is better than simpler

echo "something" | sudo /bin/tee /etc/config_file >/dev/null

already mentioned as a suggested way of handling this?

What you proposed still uses external binary (tee), still requires
redirection of standard output and in addition uses additional
features of sudo not required when using simpler form.
