No, because that would give problems with `customize-changed'. For packages included with the Emacs distribution the :version keyword should be the first released version of Emacs that contains the defcustom with its current standard value. Note however that a defcustom needs no :version keyword if the :version is the same as that of the defgroup. Defcustoms in packages not distributed with Emacs should have no :version keyword. `M-x customize-changed RET 21.4 RET' is supposed to show the user all defcustoms that were added, or whose standard value changed, in Emacs 22.1. That is the main purpose of the :version keyword. Of course, the fact that you get a 2811 line long Custom buffer limits the usefulness of this feature. Once upon a time, when Emacs releases used to be much more frequent than they are now, `M-x customize-changed' was one of the most useful things to do when a new Emacs version came out.
