Answer
Yes — Aurena still uses profiles under the hood, and the home-page configuration for Aurena specifically lives under the 'ifsweb' context/folder rather than being purely a per-user Recent-Screens setting. This gives a shared, profile-level way to configure a home-page Lobby for a group of users in Aurena, analogous to setting it via Base Profile in IEE, rather than needing to configure it individually for every user.
