In general, I agree with the idea of exposing the translation of unbound
event-modified keys to Lisp functions that can process untranslated keys.
Maybe it would be possible to implement the following interface to define
such bindings?
(define-key global-map [(shift untranslated)]
(lambda ()
(interactive)
(when (and transient-mark-mode (not mark-active))
(push-mark-command nil nil))))
