The MultistepController is difficult to extend because everything is built within the rebuildForm method. If you only need to modify the buttons, you must implement hook_simple_multistep_controller_alter, which involves overriding both the class and the entire rebuildForm method.
For example, if you want to add one more button—such as a “Draft” button—you must override the entire method just to include this new button. This approach can be problematic for maintenance, since future versions of the module might significantly change the rebuildForm method, forcing you to update your custom code to remain compatible.
Of course, there are other ways to achieve similar results. However, following the module’s recommended approach to extend MultistepController via hook_simple_multistep_controller_alter, the class could ideally be structured to break down features into smaller, more manageable pieces.
We could separate the method in functions, like:
public function rebuildForm(array &$form): void {
$this->addStepIndicator($form);
$this->addButtons($form);
$this->addFormText($form);
$this->processSteps($form);
}Then, if I want to modify the the buttons I just have to override the addButtons method.
