Conference Control mechanisms and Conference Control applications should be separated. The mechanism to control applications (mute, unmute, change video quality, start sending, stop sending, etc) should not be tied to any one conference control application in order to allow different conference control policies to be chosen depending on the conference domain. This suggests that a modular approach be taken, with for example, a specific floor control modules being added when required (or possibly choosing a conference manager tool from a selection of them according to the conference).
