Comment (by dgoulet):

 Replying to [comment:22 mikeperry]:
 > Hrmm, I am not sure how to differentiate the v2 vs v3 calls+data. What
 is the convention for that?

 Within the circuit, v2 has a `rend_data` and v3 has `hs_ident`. One
 circuit can _not_ have both. If none exist also, it is not an HS circuit.
