New FCP-plugin for Canon DSLR-shooters

There is a new EOS plugin for 5D Mark II, 7D and 60D owners. Where does that leave us 550D and 600D users? Why not a plugin for all DSLR EOS cameras? Or do we 550D/T2i owners have to change scripts in the plugin folder again as we did for the first EOS plugin? The ways of Canon are mysterious sometimes. (and often frustrating- ever tried to find something on their websites?)
Here is an explanation why this plugin should be a great improvement over the first one.
