I wonder how many federations are in this category... Any numbers?
Wouldn't it be easier to kindly ask them to change their behaviour
instead of investing a lot of time in
specification/implementation/deployment of a new meta attribute that is
only mitigating and not solving the problem really (see below)?

Isn't that the most reasonable approach, combined with some logic on the
SP that throws an error message e.g. if neither displayName, commonName
or givenName+sn is available even though the name is crucial for the
operation of the service?

But there still will be a problem with mari, right. Namely, if the
webinar service requests a name and an identifier attribute and if an
organisation can only provide an identifier attribute. I have heard that
in some countries/federations, many IdPs can release hardly more than
affiliation and ePPN.
