Hi Shane,

While I agree that halting all collection should not be our goal, I
believe that these discussions are useful. I try to put them into
perspective:

My perspective in general is:
- Our working group is called "Tracking Protection" for a reasons:
  It aims at addressing user's privacy concerns around tracking.
- This includes a concern about  behind-the-scenes exchange and
   correlation of information from different contexts.
- I agree that this is hard and that none of our rules will be perfect

My perspective on the exceptions is:
- The ideal effect of DNT;1 would be 'no tracking whatsoever'.
- This would break some mechanisms that are desired or required
   while needing some amount of tracking.
- We now what mechanisms we want to keep (the exceptions)
- For those mechanisms, we do not want to give a free ride
  like "if you want to do [mechanism],  then you can
  continue all tracking as usual"
- Instead we want to provide a cost-efficient
  way to keep these mechanisms while keeping
  as much privacy as efficiently possible

To summarize:
1. We need to decide what exeptions to make (what
    potential trackings not to break under DNT;1)
2. For those mechanism we need to understand
    today's best practices
3. For these benchmark best practices, we need to find a way
    to balance cost of implementing changes with
    the privacy risk/gain

Note that I believe that it is important to understand today's
practices: Otherwise, we may make constraints that are expensive to
implement while not providing privacy gains.


Just my 2c,

matthias
