 From https://trac.torproject.org/projects/tor/ticket/31740#comment:7:

 >One concern is that the different parameters (etag, timestamps...) might
 be leaking enough info about the user state that it allows linking
 together requests done over time as belonging to the same user. In
 principle, the request parameters depend on the values returned in
 previous responses, and these seem not to change very often. I did not do
 a deep analysis, but I feel like we would not lose too much by doing the
 same requests without parameters (as if there was no previous state in the
 browser). I don't see the responses being so big, nor the requests done so
 often.
