This is actually what POSIX specifies (see vi(1p) or [1]), following the
traditional behaviour.

The vim documentation states

    Vim interprets "cw" as change-word, and a word does not include the
    following white space.

I think of "regions" in vi as more of an implementation detail, which
doesn't belong to the editing paradigm (contrary to vanilla emacs).
