The argument is for people who do not want to be visible.
It is their identity which could be like a medical record.
Indeed, at start everyone could have such. And by individual consent they could enter a public space of the lectures.
But some may feel not to be even on the video records.
If the above is done, no discussion from the beginning about identity and subsidies!
Also, a medical record needs a trusted person, that is trusted by the subsidisers and the (individual members of the ) organisation.
In this case: if I say that YaoWei did a good job, I make him implicit such a trusted person.
Whatever: behind the scenes there will be people who do not want to enter a public space of naming.
I only plead to make it explicit. And the trusted person could be useful also for not writing down too complicated rules.
With friendly greetings,
Peter van Summeren
