Comment:

 I do not think this is an issue in HSv3 because a service intro circuit
 that never establishes ultimately get removed by
 `circuit_building_expire()` and the HS subsystem notices it at that point
 which results in opening a new one.

 No descriptors are published without all IP established.

 As for v2, I believe it should also behave like that but uncertain. In any
 case, not sure we'll fix this in v2 unless major stability or reachability
 issue arise?

 Please re-open if I'm wrong but in the end, I think
 `circuit_building_expire()` does its job properly.
