This is a reasonable argument, but then the other solution would be to opacify the data on the spot and/or not record them at all.
Which one is the most reasonable? 

Shutting down options without proposing new ones doesn't help the discussion.

[JC] Keeping a separate set of logs and applying a DNT retention period to that set of logs seems like a reasonable approach. However, it will take time to modify systems to support this change. De-identification is another possible approach, though we need to specify the level of de-identification that is acceptable. Unlinkability could be a good measure.

exceptions of which nature? opt-in cookies and/or opt-out cookies. 
It might be interesting to develop a solution where this is manageable by sites. STill need to think about that.
