The ruby patch is a special case – it is known that the paludis ruby bindings break with 1.9.2 series and I view that patch as being more of a reminder to fix the bindings / check if newer ruby versions self-fix.
Maybe encourage contributors to test patches for repositories they don’t have push access to. Let those with push access decide how much trust to put in ” patch /34748/ works for me, maintainer_nickname”
