Error for delete query without alias since 2.6.0

This used to work with 2.5.x:

$em->createQueryBuilder()
    ->delete(MyEntity::class)
    ->getQuery()
    ->execute();

Now with 2.6.0 I get this error:

[Syntax Error] line 0, col -1: Error: Expected Doctrine\ORM\Query\Lexer::T_IDENTIFIER, got end of string. (Doctrine\ORM\Query\QueryException)

If I add an alias it works again:

$em->createQueryBuilder()
    ->delete(MyEntity::class, 'e')
    ->getQuery()
    ->execute();

Is this BC break intentional?
