This model works well in universities, where you associate some resource
when a student logs in, or a virtualised environment (like a UML or
vserver), where you attach resource to the root process.
It doesn't work with web servers, database servers etc.,, where the main
application will be forking tasks for different set of end users. In
that case you have to group tasks that are not related to one another
and attach resources to them.
Having a unified interface gives the system administrator ability to
group the tasks as they see them in real life (a department or important
transactions or just critical apps in a desktop).
It also has the added advantage that the resource controller writer do
not have to spend their time in coming up with an interface for their
controller. On the other hand if they do, the user finally ends up with
multiple interface (/proc, sysfs, configfs, /dev etc.,) to do their
resource management.
