@Gourleyo, that was something they explored, but some of the changes were impossible to dual support, as it defeated the whole point, in streamlining the skin, improving the backend caching, and saving everyone bandwidth.

Thats why some of the skin problems that were seen above happened, some of these could not be caught until it was in the full production environment and both the front (the skin) and the back (the new caches) were live at the same time.
