That's good news, they used to have that code in /etc/zshenv which
meant you had _no_ way to override it. It only took them a few years
to fix this.
As a sidenote, it's not a great idea to set your path in .zshenv, you
should probably move those settings to your .zprofile. (Otherwise,
running a script that uses zsh will not use the $PATH from the
environment, which can break things in some situations).
