Having a configuration like this:

        'related_posts' => [
            'exclude' => true,
            'label' => 'LLL:EXT:blog_example/Resources/Private/Language/locallang_db.xlf:tx_blogexample_domain_model_post.related',
            'config' => [
                'type' => 'select',
                'renderType' => 'selectMultipleSideBySide',
                'size' => 10,
                'autoSizeMax' => 30,
                'multiple' => 0,
                'foreign_table' => 'tx_blogexample_domain_model_post',
                'foreign_table_where' => 'AND ###THIS_UID### != tx_blogexample_domain_model_post.uid',
                'MM' => 'tx_blogexample_post_post_mm',
                'MM_opposite_field' => 'related_posts',
            ],
        ],

the table isn't created.
The culprit here is the option 'MM_opposite_field', removing it, it works like expected.
