Some things I’m still not seeing answered in the basic spec:
- 
Could a theme bring its own custom plugin outlets? 
- 
Reiterating what @Oskar asked: 
Do we want to support custom templates in the v1 of themes? I certainly think it makes sense to bundle that in there. For example, if you style your theme around a custom desktop_category_page_style that you’ve added, the template and theme are basically codependent.
