I don't think is a good recommendation until rend.Page stops always
handling an additional empty segment regardless of the value of
addSlash. This behaviour has already been deprecated but not yet
removed. See nevow.rend.Page.child_.

Right now, there's no way the developer can know if the URL the user
used to reach the page is /foo or /foo/ and that makes it difficult to
construct a correct relative URL.

I guess it's time to remove the deprecated child_ stuff.
