No, you aren't. There are many Tramp users running a remote shell in
Emacs. But this is not the majority of Tramp users ...

I do not want to write an example which does not use the default. People
tend to copy example lines, and I want to encourage them using the default.

As compromise, I have rephrased the manual:

--8<---------------cut here---------------start------------->8---
          When using zsh on remote hosts, disable zsh line editor
          because zsh uses left-hand side and right-hand side prompts
          in parallel.  Add the following line to ‘~/.zshrc’:

               [[ $TERM == "dumb" ]] && unsetopt zle && PS1='$ ' && return

          This uses the default value of ‘tramp-terminal-type’,
          ‘"dumb"’, as value of the ‘TERM’ environment variable.  If
          you want to use another value for ‘TERM’, change
          ‘tramp-terminal-type’ accordingly.
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
