There are a lot of cases where it is validated, for example
if you used first a regular expression to filter lines. There
are also a lot of uses where doesn't mind the difference
between 0 and no integer (for example sort -n). There
are also a lot of cases where 0 is not a valid value.

'should never be used' is not a very general sentence.

But, ok. This is a personal taste (this and the other question
about strlcpy), and I don't want to begin a war.
