I didn't like the inconsistency of using one approach for variable names and one for method and property names in PHP classes (which were always camel-case). + +I'd have had code like this with a mixture of both: + +```php +class MyClass { + + private EntityTypeManagerInterface $entityTypeManager; + + public function __construct(EntityTypeManagerInterface $entity_type_manager) { + $this->entityTypeManager = $entity_type_manager; + } + +} +``` + +Or even more simply: + +```php +$entity_type_manager = \Drupal::entityTypeManager(); +``` + +I prefer not to have to consistently think about which to use and, if possible, like to use standard approaches in different codebases whether I'm working on a Drupal project, a Symfony project, or a PHP library. + +Plus, I get to use new PHP features like [promoted constructor properties](https://www.oliverdavies.uk/archive/2023/04/12/cleaner-php-code-with-promoted-constructor-properties) if everything is named in the same format.
