Yanis Varoufakis is politically toxic as far as Europe's political and financial elite are concerned.  Anything involving him will immediately be dismissed as:

1. academic
   
2. not serious
   
3. wrong headed.

So yes, if a Seuro actually emerged from any discussions involving him it would come as a complete shock to Europe's elite as they will have steadfastly ignored everything involving him. He could have been blogging about it for months and presenting academic papers on the topic, and it would still come as a shock to them.
