I don't think so.  There is no need.

To make language clearer, let's say the variable is foofoo, its defcustom
is in foofoo.el, and all its other uses in Emacs are in foofoo.el 
after the defcustom.

That option doesn't have any problems, I think.

Setting it with (setq foofoo ...) is something that should work
in .emacs.  But we don't say it will work in Lisp code in general.
To do that, the user has to look up the right way to set it and do it that way.

So I think what I proposed is correct.
