I definitely see the use of the option.

However, the above isn't the target for _any_ of the Fedora Editions,
except _maybe_ "Developer in a large organization" for Workstation, and
even then I think it's not likely to be the above.

"On desktops and on servers: unless the admin permitted it explicitly,
there should not be user code running" is a fine statement of policy,
but it's _definitely_ policy, not fact, or even generalized best
practice. 

Disabling user accounts and logging someone out seems like a separate
management problem not necessarily addressed by this anyway (how do you
ensure logout on all systems?).
