Is there a crazy reason that why a project owner couldn't from the server side define 7 or so different sane default versions of their GUI and serve them at random from the same download link so that some of the work would be put to use? As we are now working in the post-Bootstrap era, if I ever put out a GUI library, I think I might do just that.
