EntityViewsData does not generate a "delta" field for multivalue base fields

views_field_default_views_data() generates a delta field for multivalue configurable fields.
This is very useful when adding a 1:N relationship, as it allows to select only the first item (e.g. show a product and its first/default variation).

EntityViewsData has no such code for multivalue base fields.

Relevant views_field_default_views_data() code:

      // Expose additional delta column for multiple value fields.
      if ($field_storage->isMultiple()) {
        $title_delta = t('@label (@name:delta)', ['@label' => $label, '@name' => $field_name]);
        $title_short_delta = t('@label:delta', ['@label' => $label]);

        $data[$table_alias]['delta'] = [
          'group' => $group,
          'title' => $title_delta,
          'title short' => $title_short_delta,
          'help' => t('Delta - Appears in: @bundles.', ['@bundles' => implode(', ', $bundles_names)]),
        ];
        $data[$table_alias]['delta']['field'] = [
          'id' => 'numeric',
        ];
        $data[$table_alias]['delta']['argument'] = [
          'field' => 'delta',
          'table' => $table,
          'id' => 'numeric',
          'additional fields' => $additional_fields,
          'empty field name' => t('- No value -'),
          'field_name' => $field_name,
          'entity_type' => $entity_type_id,
        ];
        $data[$table_alias]['delta']['filter'] = [
          'field' => 'delta',
          'table' => $table,
          'id' => 'numeric',
          'additional fields' => $additional_fields,
          'field_name' => $field_name,
          'entity_type' => $entity_type_id,
          'allow empty' => TRUE,
        ];
        $data[$table_alias]['delta']['sort'] = [
          'field' => 'delta',
          'table' => $table,
          'id' => 'standard',
          'additional fields' => $additional_fields,
          'field_name' => $field_name,
          'entity_type' => $entity_type_id,
        ];
      }
