Impossible (unless you either unset it yourself or have very broken
version). (Value of) IFS is used to split input line into words in some
contexts; I am sure about `read' builtin and possibly some others
(select?). By default it is set to space, TAB and LF for sure; I am not
sure if \0 is Zsh extension (anybody cares to lookup in SUS?)

Zsh itself does not depend on its value. But you may have some scripts
that expect it to contain \0.
