            <title>[SERVER-38527] Reduce the number of supports*() functions for timestamps in the storage engine API</title>
                <link>https://jira.mongodb.org/browse/SERVER-38527</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Today in the storage engine API, there are many supports*() functions for enabling timestamp support. We can reduce these down to one function called supportsTimestamps() and remove the additional ones.&lt;/p&gt;</description>

Until we remove support for majority read concern off, there is not much we can do here in terms of merging these two functions. I will be closing this as won&apos;t do.&lt;/p&gt;</comment>
