While I agree with Ber that we shouldn't force one workflow in core, we do
need to establish a common data model for it. Otherwise, there's no way for
contrib modules to arbitrarily tie into it. Right now, some contribs just
store nid. Technically that's wrong because then versioning doesn't work;
they need nid and vid. If we want "drafts in core", then we also have to
have some mechanism for contribs to "just work" with whatever the draft
mechanism is. (A did column? Just reusing vid? Actions in core? Something
else? I don't know.) If we don't, you'll be able to save-as-draft the title
and body and little else, which is rather pointless. :-)

"If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an idea,
which an individual may exclusively possess as long as he keeps it to
himself; but the moment it is divulged, it forces itself into the possession
of every one, and the receiver cannot dispossess himself of it." -- Thomas
