 Another related set of questions involve what parts of already organized domain stacks should be "promoted" to the ecosystem level (i.e., Scientific Python). For example, would it make sense to merge discussion forums (using categories and tags to keep things organized); governance structures; and codes of conduct standards, reporting guidelines, and review committees.
