The following prints the words "dangerous" on emacs -Q.  Also if I
replace "/sudo::/" by any of the ssh hosts I have access to.  This isn't
expected, is it?

(let ((default-directory "/sudo::/"))
  (setq-local process-environment (cons
                                   (concat "PATH=/dangerous:" (getenv "PATH"))
                                   process-environment))
  (shell-command "echo $PATH" t))

I was just saying there's perhaps an analogy here.  "Project-local
variables" isn't a thing, as far as I know, but perhaps something like
that could be introduced.  I'm not trying to make a concrete suggestion
right now. :-)
