"Not really - with DHTs, there's nothing stopping a peer retrieving the entire
contents of the hash table."

and it (list of IPs) is not going to prove
anything. tracker can generate random IPs from time to time or simply database
contains "old" IPs.  adversary will fail to establish any additional connections
and check that peer exists and is accessible. Peers are satisfied sitting
in their sub-swarms and do not accept connections from anybody outside the
list received from the tracker. 

Think also about secured BT, where access
to the data should remain restricted. Today typical BT client accepts connections
from everybody and "leaks" data to the outside world.


"...anonymity isn't
a design goal of BT"
indeed. security could be one of goals.

P.S. tracker
is expected to be aware of missing in sub-swarm blocks and makes required
adjustments.
