DNT-policy is too permissive in certain cases

After being caught up in the net of being tracking services we posted the /.well-known/dnt-policy.txt and are perfectly fine with it for some services. However for other services we have a very simple policy. We do not track _ever_ unless there are specific technical reasons we need to. Of course we are in compliance with the posted policy, but having such a permissive policy seems to suggest that we are doing a lot less to protect users privacy than we are actually doing. We would suggest two additional policies in addition to the Do Not Track Compliance Policy.

# Do not track policy.
Outline:
We do not track you unless we have specific technical reasons.

This is the policy we would like to use.

# Do not track policy - strict.
Outline:
We do not track you.

We think this too strict and difficult to follow through in practice, but it should exist as an option.

Start by reading the existing /.well-known/dnt-policy.txt and compare its language with the two proposed outlines in this issue. Add the non-tracking and strict policy variants where this repository publishes policy text, and consider the work done when both options are clearly documented and distinguishable.
