There's a difference between customers and vendors here. It would be a waste of resources for a customer to upgrade to every new Ubuntu release. We're at the stage in 12.04's lifecycle at which customers should ideally have their plans to upgrade from 12.04 to the new 14.04 LTS solidified. If you use one of the packages the author mentioned, you can't upgrade because they don't yet offer support for the new LTS.
