Using Nats with Nat control off

Is there any downside to using NATs (in particular NAT/Global combos) with Nat Controll off?  It is the default setting for the ASA and I haven't noticed any unusual behavior.  I have 6 vritual interfaces and only have the nat/global pair setup for traffic flowing from one of the 5 inside/dmz interfaces to the outside.

If you're asking: is it okay that traffic between inside interfaces is not natted and the only traffic that gets natted is the traffic leaving the outside interface, then the answer is 'yes', that's preferred.

On other Cisco firewalls, I've had to disable nat between two non-outside interfaces.

That pretty much confirms what I was seeing.  Thanks.
