Such applications run with super-user privileges and has full access to all private memory of all processes and sensitive user data. This is a huge security breach. 2. It can easily kill KDE/Gnome shell or VM hypervisor, which can cause data loss. 3. Some implementations are killing all processes with the same name[1] and their developers think that this is a feature. 4. Super-user daemons should not touch userspace at all. A real user-space OOM should run with privileges of the same user using system-user units.
