Yes.

To inherit implies that it is a child of XWin, so no.

However, you can create a process with an identical login environment by
requesting the shell to create a login environment.

Reading 'man zsh' would save you having to guess.

The login environment is nothing to do with startxwin.  You are requesting zsh
to create the login environment with the '-l' flag.
