I would be very interested in seeing people experiment with more specific warrant canaries. Many of them currently are of the form, "This service has not received any of these kinds of orders at any time before YYYY-MM-DD." What if instead, to go to an extreme (though it could be somewhere in between), each user could check a page that had a long list of statements regarding their account, e.g. "We did not comply with a {TYPE} order between 02:00 and 03:00 GMT on 2017-02-17 that affected your account." Obviously that's poking the surveillance bear more than a really broad canary (ooh, big deal, now people know X provider with 100 million users received an order within T time of the last update to the canary), but I'm not sure that it's qualitatively different.
