Hi Ronan,

Quick question: Do you only need a change in collection/retention time 
to 48h
or would you also require to set a ID cookie?
(i.e., loosely speaking "acting like DNT;0" for 48h and then cleaning up)?

In the latter case (also 48h permission to set cookies), I would need to 
change the proposed text for this permitted use.

Just to remain clear from today's call, I'm not sold on the "P" flag. 
  The technical need appears limited (especially if ID cookies aren't 
allowed for DNT: 1 and no consent), and the risk of abuse seems not 
insignificant.
