Yes.

What zsh does depends on context. The simple example in that web page
(emacs ...; cp ...) behaves like WCE if emacs opens the terminal, but
behaves like WUE if emacs runs in GUI mode. For a process at the end
of a pipeline like Dima's original example, zsh does IUE. Interactive
shells with shinstdin (e.g. not reading a script file) also do W?E.
Most of the time a zsh script is going to perform IUE and an interactive
shell WCE, because that's how we interpreted the "inherited from parent"
signal handling was required to behave.
