Not in advance, but it will be interesting to see whether we have observations of them.
We (and other people who care about certs) could probably use contributions of algorithms for detecting things that are suspicious about certificates. :-)
One thing that I believe is not yet implemented but that I should try to implement is finding observations in the Observatory that, if they had been made by Chromium, would have violated a cert pin in Chromium. (Most of the observations in the Observatory are made by Firefox users, so their browsers wouldn't notice a pin violation at the time the observation was made.)
Another thing that could be interesting is finding all apparently valid certs that have never been seen by any Perspectives notary.

Anyway, there are a lot of queries to be run!
