Presumably you will actually try connecting to it, no?

And what happens when someone changes the setting on the master from
hot_standby back to archive?  I'd rather have the reporting server
continue recovery without being able to accept connections rather than
die in its tracks.

I think this is a problem that should be solved by monitoring, rather
than by automatically taking the server down.
