Save the 10 model limit. The recent addition of the tools to help with "bottom up" design provides a nicer workflow for a lot of cases, but would prevent you from having more than nine components in your assembly (the assembly being the 10th) which seems too little even for the smallest of hobbyist projects. It would be reasonable if there is an exception for models included in an assembly. Apparently that restriction is not coming until next year, so time will tell.
