Sure it is, because the later can be controlled by policy.

Hence the ability to define policy.

But can you elaborate more on "root for all purposes"? I'm not aware of any
programs in Fedora which, when installed, make a user root. Barring any
security holes, of couse. One still wouldn't be able to start or configure
services without further authorization.

If you're limiting to installation, sure. But more fine-grained control than
repository level might be desirable.

This is a good argument *for* the idea.

Users can currently install whatever random stuff they want in their home
directories. They can build their own local versions of network clients and
then fail to upgrade them to fix security flaws. Much better to allow them
to install selected programs from the official Fedora repository.
