Comment (by akwizgran):

 Perhaps the problem could be solved by using the hash of the identity
 public key, rather than the blinded public key, to identify the service in
 the state file. This would make it possible to remove any stale entries
 for the same service when storing the incremented counter, without
 affecting any entries for other services.

 However, this would allow entries for ephemeral services that are no
 longer used to accumulate in the state file. This seems difficult to
 avoid: on one hand we have to keep state for any service the controller
 may one day want to reactivate, while on the other hand we'd prefer not to
 accumulate state for services the controller no longer intends to use.
