Revert "Keep a place, and come back to it"

This reverts commit bd3a5a4. The bookmarks work was committed onto this branch
by mistake — it belongs to its own pull request, and it has one, branched from
this branch's own tip. Reverting rather than rewinding because the branch is
published and a pull request is open against it: the diff this pull request
shows is what matters, and after this it shows the routing change alone.
