Really?   Next time I will consult with your authority on what works and 
does not work in production environments before implementing for 
large-scale billing solutions that are perfectly functional, and indeed, 
very much in production.

By the way, there are, of course mitigating strategies to minimise risk. 
  Dialog-stateful modules can end the dialog after a certain timeout, 
you can send periodic re-invites with an SDP offer to probe the 
endpoints, etc.

It is far wiser than introducing a point of failure, a source of 
latency, and a source of huge bandwidth and processing cost into the 
call path when you don't need it.
