Here are my WIP specifications for these:

;; - other-working-trees ()
;;
;;   Return a list of all other working trees that use the same backing
;;   repository as this working tree.  The members of the list are the
;;   absolute file names of the root directories of the other working
;;   trees.
;;
;; - add-working-tree (directory)
;;
;;   Create a new working tree at DIRECTORY that uses the same backing
;;   repository as this working tree.
;;   What gets checked out in DIRECTORY is left to the backend because
;;   while some VCS can check out the same branch in multiple working
;;   trees (e.g. Mercurial), others allow each branch to be checked out
;;   in only one working tree (e.g. Git).
;;   If a new branch should be created then the backend should handle
;;   prompting for this, including prompting for a branch or tag from
;;   which to start/fork the new branch, like `vc-create-branch'.
;;
;; - delete-working-tree (directory)
;;
;;   Remove the working tree, assumed to be one that uses the same
;;   backing repository as this working tree, at DIRECTORY.
;;
;; - move-working-tree (from to)
;;
;;   Relocate the working tree, assumed to be one that uses the same
;;   backing repository as this working tree, at FROM to TO.
