It does kill your serive if your service is SSL based.

Managing more config and more daemons always increses the complexity.
More Daemons increse the probabilty of failure and increase the monitioring
More Daemons increase the probailty of security problems.
More Daemons increase the amount of time spend keepings the system up to date.

It might increase the complexity of varnish but not the system a hole.
