I think the answer is — yes, most of our customers have moved to managing third-party software themselves as they have more explicit control over versions. That we did not see high downloads of the popular packs and de-prioritized the update of it. That said, if helpful we can get an update scheduled for next month once the majority of the 2020-06 plugin updates have been made.
In addition, in recent versions of SDC we allow you to import Third Party libraries directly from the marketplace, which also make it easier to manage how you import software on your Delivery Hub. Import Third Party Libraries
