I am not a zsh user, but according to zsh's documentation, ~/.zprofile is run only when zsh is used as a login shell, whereas ~/.zshenv is read for nearly every instance of zsh (including scripts):

https://zsh.sourceforge.io/Guide/zshguide02.html#l9

Because of this, it is possible that if /opt/local/bin, etc., are only added to PATH in ~/.zprofile, then in some instances zsh would use the Apple standard programs in /bin, /sbin, /usr/bin, etc., while in other instances zsh would use, for example, the MacPorts versions in /opt/local/bin, etc.  This might lead to inconsistencies or hard to detect bugs in shell scripts, etc.
