Sorry, this discussion is important.  Your example proves my point.  What you show below is a disclosure.  It is a disclosure of a limited set of data.  we are not supposed to be talking about disclosure at this point in our proceedings.  I leave it to the experts on whether this is "thin" in the sense of the thick transition discussion, I really don't know because we are focused on gTLD policy here.  My point is this is a disclosure.  We do not "collect" thin data per se, we collect a whole mess of mandatory data elements, as per the RAA.  Then we generate a whole mess as part of activating and making real the domain's existence.  Then we share (release) a small subset.

So talking about collecting thin data is misleading in my view.  Purpose of disclosing it is what we are in fact talking about. Calling it a purpose for collection opens the barn door.

Thank you Michele, ( ignoring the spell check driven typo of "think" for "thick" (-: ). We should be able to put this "thin" discussion behind us.
The "thin" discussion should have taken about 2 email exchanges. Here is CIRA's (thin) search for .ca domain names [disclosure: it is my domain name]

Nothing private is disclosed and LEA would have to resort to legal means to get to what is in the "thick" data set.
There are no ICANN policy  issues here.
