 > This seems an odd question. CollecTor serves tarballs of the published
 descriptor data. If the authorities publish it then CollecTor should
 provide it, malformed or not.

 Of course, clients should deal with the data as it is collected.
 Currently, they are 'shielded' from non-conformant extra-info decriptors,
 b/c CollecTor drops them. After the change some might trip over that newly
 available data. I intended to find out what the change would trigger, for
 example what additional work we'd have with clients like Onionoo etc.
