Are multiple Island spaces possible?

I'm not sure how closely this repo follows the original Island repo, but I noticed that in the most recent Island release, it states:

NEW: Support multiple Island spaces in app UI. (Manual setup is still required)

Meaning, any single app can now be cloned more than once. Is this possible in Insular? Will this functionality be pulled from Island? Also, just wondering what the general/approximate lag period may be for Island releases to be pulled into Insular?

Thanks for your wonderful work here! I really appreciate what you've created, because your implementation really provides a sense of comfort.
