There are modules which try to integrate with all (entity) forms and want to store data for a newly created entity upon form submission.
Node module's node_form() uses both button-level and form-level submit handlers, because it needs to take the "Preview" case into account, which does not create a new entity upon submit.
When hitting "Submit" (not Preview), then the button-level submit handler invokes all form-level submit handlers first. This means that the new node has not been saved yet, so form-level submit handlers do not have a 'nid' or $node to work with.
For example:

// Append a submit handler to store Mollom session data. Requires that
// the primary submit handler has run already, so a potential 'post_id'
// mapping can be retrieved from $form_state['values'].
// @todo Core: node_form_submit() uses a button-level submit handler,
// which invokes form-level submit handlers before the node/entity is
// saved, so $form_state does not contain the new node ID yet. There is
// no #post_submit property or form processing phase, we could rely on.
// Potentially applies to other contrib entities, too.
if (isset($form_state['build_info']['base_form_id']) && $form_state['build_info']['base_form_id'] == 'node_form') {
$form_submit_key = &$form['actions']['submit'];
}
else {
$form_submit_key = &$form;
}
$form_submit_key['#submit'][] = 'mollom_form_submit';
This is a can of worms.
There are various kinds of submit handlers:

Wonder after 12 years if still a valid task ?
