Add one minority opinion that says that the distinction between first and 
third parties is too complex. This mixes technical and legal consideration 
into an indigestible brewing. It will make implementation on the service side 
too complex. It will create risk and ambiguity. 

I would rather tone down the compliance requirements for all and not 
distinguish between first and third parties to avoid the difficult 
distinctions. (I can generate a number of challenging distinctions on demand)

I also believe that this will create a race into being a first party and that 
every ambiguity will be used to become a first party. At the end of the day, 
everybody will be a first party by contract or other virtue.
