Tentative marks capture the familiar semantics much more precisely than transient ones.By making it impossible to recreate a mark where one had been last time? What's the advantage in providing strictly less functionality?
Having looked at it more closely now, I would even suggest that transient-mark-mode be deprecated (as in dis-recommended for use and of low priority for compatibility, going forward).)I don't get your point. You basically want to remove functionality and sell this as an advantage under a different name.
