IsPreventAdminlessGroupsEnabledUseCase
interface IsPreventAdminlessGroupsEnabledUseCase
Use case that reports whether the backend-driven "prevent adminless groups" policy is enabled for the current user.
When enabled, clients are expected to block actions that would leave a group conversation without any admins — for example, the sole remaining admin attempting to leave the group. Callers should consult this flag before initiating such flows and present the user with alternative options (promote another member, delete the group) when it returns true.
The value is sourced from UserConfigRepository and reflects the most recently synced server feature configuration.
Return
true if adminless-group prevention is enabled for the current user, false otherwise.
