Stock validation "$stock <= 0" on the commerce_simple_stock_form_commerce_order_item_add_to_cart_form_alter() hook changes the form submit access. Since there are other modules that can interact with this hook we should make a validation on the submit action and let the other modules do their own stuff.
Actual validation:
if ($stock <= 0) {
$form['quantity'] = NULL;
$form['actions']['#access'] = FALSE;
$form['outofstock'] = [
'#type' => 'textfield',
'#value' => t('Out of Stock'),
'#weight' => 0,
'#disabled' => TRUE,
];
}
Example module: https://www.drupal.org/project/commerce_wishlist → - adds the WISHLIST button in the form actions. If we put '#access' to FALSE the wishlist button is not rendered.
Install and configure wishlist module with simple_stock and add a configure a product without stock.
Change the submit button attributes.
Actual validation:
if ($stock <= 0) {
$form['quantity'] = NULL;
$form['actions']['submit']['#attributes']['disabled'] = 'disabled';
$form['outofstock'] = [
'#type' => 'textfield',
'#value' => t('Out of Stock'),
'#weight' => 0,
'#disabled' => TRUE,
];
}

Tried the approach as mentioned above, and it's very clear that #access = FALSE will heavily impact the other module such as Commerce Wishlist → . I pulled out your MR!4 changes and seems like a nice approach to disable the cart for that specific module functionality. Hence reviewed.
