DDC-2034: getPartialReference returns partial entities for non existent entities

[doctrinebot]

Jira issue originally created by user deatheriam:

$variant = $em->getPartialReference('Entity\Variant', -1);
echo $variant->getVariantId();

prints -1. Is it an expected behavior or a bug? Shouldn't a check be made to prevent creating new instances for ids that do not exist?

Well, the purpose of getPartialReference is to return a reference without querying the database. So it cannot know if the id exists.

Ok, in that case a user is responsible for providing a valid id. But what is a use case for such an entity? Can someone give me a real example?

Comment created by @beberlei:

the use case was partially removed by proxy objects now being capable of returning the id without querying.
