So to make sure we are on the same page you are initially maintaining both guide - the current one (active/ passive) and the new one, which uses the new service. But wan't we us - doc'ers maintaining it as any other doc on the website?
For instance my production architecture uses a similar setup and Florian's guide has been of a great help, I really think both implementation can and should exist , since in the end this is not so much an update rather one another way to consider you HA deployment
