The issue with this is, that from a risk perspective (client-side), they 
are the same for P3P. Unless you have a wallet within your P3P client, 
you may not know how and what they collect direct from you or from 
protocol information etc. 

Additionally, it gives services to get away with a huge list of 
collections but hiding behind the "may". Saying, we collect race, 
political opinion, etc is different from saying: we may do that in some 
exceptional circumstances and we may (or may not) use it. In this case, 
you can't know what is collected and used as the "may" opens the can 
and everything "may" be collected, but P3P has rather to look into what 
is "actually" collected.

Problem here is that marketing isn't always following those thoughts ;)
