As Martin suggested, why couldn’t the enterprise admin not tell the UA directly not to do whole screen sharing, without having to rely on the good will of the application to carry that instruction?

Why does a well-behaved application need means to protect the user from
This is about protecting the users from themselves many enterprise collaboration applications have the option for the enterprise admin to create a policy such that users cannot share the whole screen to prevent the accidental leaking of information. I believe this is a commonly applied enterprise policy.

If the policy limits them to the well-behaved application only, then where's the harm? If not, then where's the protection?

Huh? The idea here is that Firefox and the application can in principle share the
whole screen, but the enterprise admin thinks that's not safe and so he wants the
application to tell Firefox never to do so. This avoids the user accidentally selecting
the whole screen.
