Allow easy move & change order with $page API 

Semething like:

$page->moveAfter($page);
$page->moveBefore($page);
$page->move($parent); // at end of collection

This is on the list of additions for 3.0. https://github.com/ryancramerdesign/ProcessWire/issues/1508

Edit: 

I think your last example is what actually happens if you just change the parent of a page.
