Actually for every kobj_type structure, not for every kobject. Doing a quick scan through the kernel I found 25 kobj_type decelerations so that would add up to 100 bytes only. And that could be made a byte or flags field.
I wasn't sure if it was possible to create a subsystem that wasn't a part of the sysfs tree that contained kobjects that were. Looking trough the code again it looks like it is so I'll use the hotplug filter as you suggest.
