I don't think it is a good idea to register driver for specific usages/reports. Quite often you want to adjust processing of a report for a specific device. What if there are 2 devices that need such quirks? How will you do hotplug and module loading? Emit new uevent for every report? Also, what about users and Kconfig? "Driver for usage 0x000012345. Say Y if your hardware does not wotk correctly with defautl handler for this usage and require special processing"???
Just register based on VID/PID and provide standard hid_default_input_event() to drivers so they would call it for reports they don't need to do special processing on.
