> Work profiles are inferior to separate user profiles, which are built-in to GrapheneOS.

Different use cases. User profiles are only active when you manually switch to them, while work profiles are active _alongside_ your main profile.

So for untrusted apps that you only use occasionally and on-demand (like the myriads of travel / shopping / random services apps), user profiles are great. For apps that you want to keep in the background, such as the proprietary messaging apps that all your friends use, a work profile is much nicer.
