+1.  Finally some sense in this thread.

If there's no mark in a buffer when you use C-w
the logical behavior is to raise an error telling
you exactly that.  Emacs was wise to do this.

No mark means no region, which means no region to
kill.  (And how often does anyone see this error
when using C-w?)
___

Just as bad as giving C-w this unhelpful behavior
was redefining `kill-region' to give it the new
behavior, instead of binding C-w to a new command.
___

Having no mark is different from having an empty
region (whether or not transient-mark-mode is on).
An empty region is a bona fide region.  Killing
an empty region works; as does yanking it.  An
empty string on the kill ring affects yanking
just as one would expect.  Code can depend on it.
