                    <description>&lt;p&gt;For example, see the following regressions:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Queries.FindExclusion.ProjectionDottedField.SinglePathSixComponentsNestedArraysOfSizeFive&lt;/li&gt;
	&lt;li&gt;Queries.FindInclusion.ProjectionDottedField.SinglePathSixComponentsNe&lt;/li&gt;
	&lt;li&gt;Queries.FindExclusion.ProjectionDottedField.SinglePathThreeComponentsNested&lt;/li&gt;
	&lt;li&gt;Queries.FindInclusion.ProjectionDottedField.SinglePathThreeComponentsNestedArraysOfSizeFive&lt;/li&gt;

I planned to try to do a cherry-pick locally just to see how bad the conflicts would be and if there are any other PRs that &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71035&quot; title=&quot;Investigate regressions on simple inclusion/exclusion projections over deeply nested paths&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71035&quot;&gt;&lt;del&gt;SERVER-71035&lt;/del&gt;&lt;/a&gt; depends on that would also need to be backported.&lt;/p&gt;</comment>

We will backport your change after the rc period completes and target the dot release in 7.0.1.&lt;/p&gt;</comment>
