In general I think we should be striving to create a system that's secure by default. An open-source project that's only secure when you buy x,y,z to put in front of it is less than ideal. Though I accept that in cases like this Sloworis style attacks can potentially be mitigated by some open-source proxies too.
Maybe an OSSN or even a chapter on the Security Guide directly address this sort of setup might make sense ? - I'm considering only the aspects discussed by @ttx and @stuart directly above...
