I don't thin that any these extra ship sizes will be included in Gold Version.

It's intended to be used by many other mods and shipsets, yada yada yada, but it's nothing more than another mod.
A mod that wasn't ever submitted because it's even now unfinished.
I don't think it will ever be included as a standard part of the game.
The new secondary pic feature that we requested and will appear in gold is a good help, and will eliminate the need of the copying program in most ocasions. It will allow modders to take advantage of shipsets with extra pictures without worrying if all shipsets have all pictures.
The copying program will still be needed to, establish chains.
AFAIK you will only be able to put one second option, not 3, 4 or 5 options (like wepons in a design) in order of priority.
For example the picture for a heavy baseship is "baseshipheavy" secondary image "baseship" and third option "starbase"
Someone also mentioned that some people will never get Gold verion.
