[development] Why $form['#post'] is cloned for each element instead of beeing passed by reference ?

[Daniel Caillibaud]

Hi,

Is there any reason to a valued affectation of $form['#post'] instead of a reference affectation ?

In form.inc, function form_builder, line 892, there is

foreach (element_children($form) as $key) {
    $form[$key]['#post'] = $form['#post'];

why not just a 
    $form[$key]['#post'] = &$form['#post'];
?

Thx
