These are not new themes....they are the same old boring theme with a different font and new wallpaper. A 'theme' should incorporate all elements being changed, ie. icons, font, colours, background underlays, placements, etc.
I think what is restricting people from that right now is that it is a leaked version of plazmic and it is not allowing people to change fonts and there might be more that they are not able to do since it is not an actual version.
I don't know since I don't know how to make themes. But that is my guess.
I am working on one right now. Still working on it though. Its going to take some time because not all the options are there in the Plazmic. Like you can't change the download, games and other folders. Or the app center
