Yes, clearly an extension, optimization, or new work along the lines
of the above paper.
Perhaps more interesting is this dilemma...

So we have at least one core person who knows. Now assuming this
presentation  is in fact 'Really Bad News' for, at minimum,
Hidden Services... will the details of it be leaked in order to
'save' HS operators/users before CERTs/GOVs/LEAs/Vigilantes/Spies
and the thought police have time to get at them (or what unexposed
elements still remain of them)?
This is premised upon CERT's typical cozy relationships with LEA's,
naturally leading to sharing with them what are potentially ...
'tested ... in the wild ... dozens of successful real-world
de-anonymization case studies, ranging from attribution of'
... really diskliked things. Particularly cases of human harm
where it is only natural to seek intervention.
Then there are the cases worthy of every possible protection outlined
Therein lies the dilemma. What do you do?
[Note that even if the above relationships, or desire to intervene,
do not exist... said spies and their actors are likely to monitor
the full research details, and know who in the public knows as well.
This could lead to shorter time constraints on all sides.]
 Which I forgot to link in the OP, thanks Matthew.
