If 'false', the Spring beans for the built-in Java-based image transformation are not instantiated. The setting is for example automatically set to 'false' in a CoreMedia Content Cloud Service instance that is using the cloud-only image transformation service with WebP support. In this case, customizations of the 'BlobTransformer' are not possible and as such it helps preventing illegal configurations. The setting may only be set to 'false', if there is a plugin which provides a 'BlobTransformer'. Otherwise, the application will fail to start with a bean creation error.
