Comment (by dgoulet):

 Hrm, it could be but intro points are used for very little stuff that is
 setup the RP and after a few cells we are done. With lots of clients, it
 could slow down the "establish a connection to HS dance", yes.

 I want to point out also that the latest Usenix paper (not yet public)
 does mention that cannibalization is a useful counter measure to circuit
 fingerprinting. However, they also propose mitigation for newly created HS
 circuit (IP/RP/HSDir) so I could be convinced that a new circuit is better
 but my instinct tells me that it shouldn't be that crazy performance hit.
 Would be a good use case for OnionPerf!
