Components Maintainers and Gutenberg

In this week’s DevChat, @jeffpaul asked:

One thing I’ve become curious about is how some components should potentially be looking to support current/future phases of Gutenberg? Thinking here about Customizer, Widgets, Menus, and the like. Is there anyone on the Gutenberg team that’s working with those components to see how those maintainers/contributor teams could help advance Gutenberg development from their unique perspective from a core component team?

Some discussion ensued, but it’s an important topic that’s worth discussing in an asynchronous forum where people from all timezones can participate.

So: How do we ensure that there is good collaboration between Component Maintainers and the Gutenberg project?
