Hi Ben, Nemmel,
We’ve been doing a lot of discussing internally to explore options for the situation we have here. Introducing the new profile has shifted the paradigm for profile management. Site admins no longer have authority over the user profile, because that same account can appear in multiple sites, and it takes the same profile everywhere.
Replicating your apps in the new profile world would require an Organisation Admin to install the apps on the profiles of their managed accounts (this requires a domain claim).
Unfortunately the infrastructure for Org admins to install apps is not currently available. At the same time, we don’t have web panels on the new unified profile. We don’t expect these to be in place for at least the next 12 months.
We absolutely want the new profiles to be extensible, we’re just not there yet.
