In the [Sending Messages Async](https://symfony.com/doc/current/mailer.html#sending-messages-async) ( symfony/symfony-docs@4fbbc16 ) docs the BodyRenderer is mentioned and used in the example. But there's no alias yet, not sure if this was intentional `@fabpot`? But it would be nice if it works right away without the need to add the alias manually.
