From the updated Rules of Conduct:

   D.I.Y. & Other Permitted Content 
   In addition to content that adheres to our Creative Rules of Conduct, we have determined the following type of do-it-yourself activities are also appropriate to broadcast in Creative:

   Cooking your own recipes
   Building custom PCs
   Assembling your Twitch broadcast setup
   Furniture hacks/customization
   Model making

Huh, that's certainly a variety of things they now allow. It makes the exceptions impossible to penalize since there's a giant gray area for what's considered "creative."
