I see the point. Maybe it should be customizable somehow, whether the
hostname completion regexp is active.

OTOH, when ange-ftp was hooked into file-name-handler-alist, it was
exactly that behaviour. "C-x C-f / <TAB>" started hostname completion.
See respective (not active) code from ange-ftp:

;;-;;; This regexp recognizes absolute filenames with only one component,
;;-;;; for the sake of hostname completion.
;;-;;;###autoload
;;-(or (assoc "^/[^/:]*\\'" file-name-handler-alist)
;;-    (setq file-name-handler-alist
;;-	  (cons '("^/[^/:]*\\'" . ange-ftp-completion-hook-function)
;;-		file-name-handler-alist)))
