            <title>[SERVER-25509] Use the SingleDocumentTransformation framework for $replaceRoot</title>
                <link>https://jira.mongodb.org/browse/SERVER-25509</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$project and $addFields are both aliases for a document source that implements optimizations for 1:1 transformations. Since $replaceRoot is also a 1:1 transformation, we can leverage these shared optimizations.&lt;/p&gt;</description>
