The definition of "communities" and "ecosystems", and what role they will play in the development of open source projects feels very vague to me.
Are they seeking to create a new Apache Foundation? I can see a case for "Apache Foundation for X" type communities. But I'm of the opinion that what we really need at the moment is greater incentives for existing researchers who are already working on their projects to make their code modular, well-documented, and readable.
Larger communities such as Apache-for-X can be a second-order effect, but to make it the primary goal seems to me like putting the horse before the cart.
