Ok, when the user is in front of the laptop at typical distance, the Webapp will enable a video feed. When the user moves away, the Webapp can disable the feed. Similar control can be applied to the mic (audio mediastream).

Thanks,
Bryan Sullivan

In the user proximity case the developer may want to know specifically how far the user is, if such is supported by sensors.

With all due respect, the above is not a use case. A use case would be something like "If the developer knows that the user is X value away, then the developer can do the following things:". No one has presented "the following things" yet, specially as they relate to "min, max, value" VS "near/far" (apart to working out near/far!).
