Right. I even use this trick myself: my ~/.xsession file starts with a

	#!/bin/zsh -l

line, so that it (and everything in it) gets run after zsh has read my
~/.zprofile, including all my enviroment variables (e.g., my PATH).

This is why when I wanted my .zprofile to print a welcome message only
for interactive login shells, I did something like this in .zprofile:

# We print this message only in a shell which is both interactive and a login
# shell. Alternatively we can move this message to zshrc, inside a test if $-
# contains l (i.e., a login shell). 
case $- in
*i*)
    print "*** $ZSH_NAME $ZSH_VERSION, $VENDOR $MACHTYPE"
    print -P "Welcome to %m, %D{%A}, %D{%e %B %Y}, %t.";;
esac
