It's one thing to have a great repository of reusable, accessible, versioned, centrally managed and agreed components. It's quite another to have production systems actually using that repository, unless the DS came before building the systems.

So I'd be interested to see how this might get over the hurdle of being retrofitted into legacy systems. So many design systems I've encountered are effectively fictions: great ideas being maintained in theory, but it's next to impossible to commit the necessary operating costs to getting them into production. So the sites and apps you see may look like they're using a DS, but many of those components are "impostors" not being managed in the DS at all.
