Yes, there is benefit, but that's the wrong question.

There is no real difference between this description and an application
proxy firewall.  It's a fine design for a proxy firewall.  But the snake
oil alarms start going off when the vendors try to characterize them as
somehow different from proxies.

So while the classification of firewall types can be tedious, inspecting
the difference between "air gap" firewalls and other kinds of firewalls
really is nothing more than a nuance in firewall classification.
