To close the loop: I added a new top level page in our wiki on Governance and Operations with some links to ASF policy docs that will hopefully be helpful: link <https://cwiki.apache.org/confluence/display/CASSANDRA/Project+Governance+and+Operations>.
I've added a page under that hierarchy for this JDK version support policy <https://cwiki.apache.org/confluence/display/CASSANDRA/JDK+Version+Support+Policy> and moved some of the loose top level pages that belonged into that group.
