Just FTR, since 0.9.7.1 I2P defaults to 3 hops for "client" tunnels
(so default of 6 hops end-to-end, and 12 hops round-trip). And yes,
there is nothing stopping a malicious peer building zero-hop tunnels
(acting as its own Outbound Endpoint/Inbound Gateway), just as honest
clients or servers can choose to use zero-hop tunnels (e.g. a website
or IRC network that requires no anonymity of its own, but wants its
users to benefit).
