I suspect it depends on what you believe the point of fakephp is. My assumption was that it was a way to fake what would happen if you had a hotplug controller for a particular slot. In that context, the change I made was clearly correct. If you want to use it for hot-removing individual functions from a Linux guest running under a hypervisor (for example), that's much less useful.
