It is true that you won't be able to copy Lua-based temapltes at the moment. However, most templates are not Lua-based and can be copied just fine. As it is, Module:Mbox, as posted on the starter wiki, has some issues anyways.

Note that you shouldn't need to copy Template:!. The new platform should have a magic word for this instead. The magic word is used in the same manner as the template so you shouldn't need to adapt your usage.
