Product attribute list page should display machine names

IMO, the lack of product attribute machine names is something that is very "broken"/missing, and therefore a bug.

Consequently, this thread truly is a bug report about something missed during development, that seems intended by the existence of this essential feature elsewhere in the admin GUI.

The moment one has a large quantity of product attribute sets, all called "Color", or all called "Size", with no way to distinguish between them on the - {site}/admin/commerce/product-attributes - list except by clicking "edit" on each of them in turn to discover which is which, it is clear that this omission is a bug, and a problem of a bug, even if not a bug that causes a code crash.

Commerce 2.x needs details like this implemented in order to be a hoped for first class tool.

Based on the existing code, it seems like it would only require changing a few lines of code to include machines names in the product attribute list builder code to be similar to lists like product type list builder (see code below):

modules\commerce\modules\product\src\ProductAttributeListBuilder.php

<?php

namespace Drupal\commerce_product;

use Drupal\Core\Config\Entity\ConfigEntityListBuilder;
use Drupal\Core\Entity\EntityInterface;

/**
 * Defines the list builder for product attributes.
 */
class ProductAttributeListBuilder extends ConfigEntityListBuilder {

  /**
   * {@inheritdoc}
   */
  public function buildHeader() {
    $header['label'] = $this->t('Attribute name');
    return $header + parent::buildHeader();
  }

  /**
   * {@inheritdoc}
   */
  public function buildRow(EntityInterface $entity) {
    $row['label'] = $entity->label();
    return $row + parent::buildRow($entity);
  }

}

modules\commerce\modules\product\src\ProductTypeListBuilder.php

<?php

namespace Drupal\commerce_product;

use Drupal\Core\Config\Entity\ConfigEntityListBuilder;
use Drupal\Core\Entity\EntityInterface;

/**
 * Defines the list builder for product types.
 */
class ProductTypeListBuilder extends ConfigEntityListBuilder {

  /**
   * {@inheritdoc}
   */
  public function buildHeader() {
    $header['name'] = $this->t('Product type');
    $header['type'] = $this->t('Machine name');
    return $header + parent::buildHeader();
  }

  /**
   * {@inheritdoc}
   */
  public function buildRow(EntityInterface $entity) {
    $row['name'] = $entity->label();
    $row['type'] = $entity->id();
    return $row + parent::buildRow($entity);
  }

}
