Question National Code for Spa Installation

The National Electrical Code requires GFCI protection and a disconnect not closer than 5 feet nor more than 10 feet for installation of a spa or hot tub. I understand the reasoning behind GFCI protection; that is obvious, however, what is the logic for requiring a nearby disconnect. It would seem to me that if something went wrong with someone in the spa, you wouldn't be able to disconnect in time to accomplish anything. Does anyone know why code requires a disconnect that really doesn't provide protection to spa users?

For servicing, so the service person can shut it off and make sure nobody turns it on when they hafe their fingers in the works. The same rule applies to A/C units and many larger pieces of fixed equipment for the same reason.

There is no 10' rule with regard to the disconnect.
Here is a direct NEC quote:
680.12 Maintenance Disconnecting Means
One or more means to disconnect all ungrounded conductors shall be provided for all utilization equipment other than lighting. Each means shall be readily accessible and within sight from its equipment.
680.22(C) keeps it 5' or more away.
