Thank you for these showcases, they are great.  I'm a fan of using
session data as a baseline metric; kudos to Oliver for this work.

Is there a catalog of all data that could possibly be available (for
instance, the mw.session cookie), along with where it is logged, for
how long, and where in various toolchains it gets stripped out?

Related lists could be useful for planning:
* Limitations our privacy policies place on data gathering (handy when
reviewing those policies)
* Studies that are easy and hard given the types of data we gather
* Wishlists (from external researchers, and from internal staff) of
data-sets that would be useful but aren't currently available.  Along
with a sense of priority, complexity, cost.
