I've added the following unanswered questions at
https://wikitech.wikimedia.org/wiki/Talk:Analytics/Data/Webrequest/RawIPUsag...
1. Is the ability to rerun metrics more important than protecting reader privacy?
2. On what basis is the decision on the previous question made, or if there is no decision on the question yet, who has the authority to establish that basis?
3. Can Ops use access logs in which the article names have never been stored on permanent, non-RAM media?
4. Can the users who require logs of article names use those in which the IP address, proxy information, and geolocation has never been stored on permanent media?
