It would make sense if these were already being produced and are just now being approved for FRC, but the blog post makes it sound like they were developed specifically for FRC teams.

Breakers exist to protect the wiring, not the device. Breakers can and will pass current in excess of the rated current. If you draw 80 amps, the 40 amp breakers used by FRC will not trip before 1 second passes.
For what it's worth, the Victor 888, Victor SP, Talon SR and Talon SRX are all also rated for 60A continuous. If I remember correctly, most of the components in the Talon SR are rated for 100 amps continuous. I think it's good that a device designed for use by high schoolers is rated for more than the expected conditions.
