> pageup/pagedown should have the same expected behavior as up/down, no?

On Mac OS X, up/down move the caret while pageup/pagedown do not.  These are
quite different behaviors.  Pageup/pagedown are more equivalent to scrolling
via the scrollwheel, which will scroll the area under the cursor until it
reaches the top/bottom and then scroll the containing area.

The caret clearly cannot move beyond the start of the editable region.  Pageup
doesn't move the caret.

It may be.  I don't know what the Windows behavior is.
