According to the documentation, it seems only one Private Space can be setup by device, and only in the main user profile. Although this is a great feature that will kill the need for secondary profiles or apps like Insular for many users, this seems a bit arbitrary (at least the limitation to have just one Private Space). In my case, this feature would allow me to delete a couple of users and Shelter, saving battery, space and memory.
Is there any good reason to limit it to just one? Can/will the GrapheneOS team expand the capability?
