Yes.  I am imagine an argument between an operational person who wants to
authorization to upgrade/replace a gateway with the CFO.  This document is
his ammunition, so we need to make the CFO consider that the risks of
not updating exceed the risk of change.
Fundamentally, the CFO is risk averse, and thinks that "it ain't broken"

I want labelled IPsec to be a separate section so that it will have an HTML
link, and can be referenced easily in the government RFP that justifies the
upgrade.
