You are factually incorrect. set -o errexit is NOT best practice advice.

It is heavily disputed advice. The world is split between people who

a) think set -o errexit is the best thing ever, and is wonderful advice,
   and everyone should use it

b) think set -o errexit is horrificially horrible, a sign of incompetent
   fools, and literally the devil's work. It eats your shellscripts for
   lunch, aborts your script after completely normal commands, and
   changes its semantics in point releases of a shell. See

You had better be prepared for an internet debate nearly as heated as
the vim vs. emacs one, if you start telling people to use set -o errexit.

(FWIW, I'm one of the people who hold it to be the work of the devil, as
it were.)
