Doctrine Extensions

Configuring the Entity Manager without a framework requires manual tweaks to avoid issues, as noted in the example/em.php file, which can be error-prone for inexperienced users.

Documentation is split into separate markdown files per extension, making it harder to get a consolidated overview and increasing the learning curve for new adopters.

The event-driven architecture can add latency in high-traffic applications, especially with extensions like Loggable that increase database writes during flush operations.

Some extensions are ORM-only (e.g., SoftDeleteable) or have restricted strategies in MongoDB ODM (e.g., Tree only supports materialized path), reducing flexibility in mixed database environments.
