I have a client with a 71A00-1 hooked up to the water heater. If they remove that, the water heater is just standalone, correct? No 30A switch needed, etc?

It depends on your local codes.   My water heater has a disconnect panel next to the appliance.    It was installed about 5 years ago.     

 

My understanding is that this is to avoid having someone accidentally turn on a breaker when another person is working on the water heater.

If you remove the load control module and wire nut the incoming and outgoing 240VAC wires together (L1 and L2 separate of cource), and place a cover on the junction box, it will be like a standard install.  You'll have to terminate the 120VAC line coming into the box, or remove it.

The water heater is usually hard wired directly to a circuit breaker, no switch in line. 

There may be a service disconnect near the water heater if the circuit breaker panel is not near by.
