Does this mean that we no longer need to check & call clearAXObjectCache() in
~Document() ?

You're right.
I can see that commitIfReady() calls detach(), commitData() calls ~Document()
and commitData() is always done after commitIfReady().
I updated patchset to remove it from ~Document().

+        clearAXObjectCache();
+
     m_layoutView = nullptr;
     ContainerNode::detach(context);
