Looks like this is a no-op for now. Can you create a ticket and/or add todo comments here to make this health check meaningful?

I raised an issue here: #447
But, note, this actually already is meaningful, in that the
http.ListenAndServe()call made in the aggregator includes both the health check path and also the signature request path, so when this health check starts responding with "healthy", that's an indication that all of the paths served by thatListenAndServe()call are ready, so it tells us that the service is ready to handle signature requests.
