Yes and no, I think.

While I think much of hotplug should exist in userspace, some of it must
exist in the kernel.

sbp2 and usb-storage get devices attaching and detaching all the time.  The
SCSI core needs to be able to handle that in the kernel.

In userspace, something should get a new device notification and decide
what to do with the new device. Format?  Mount?  Ignore?  But, it needs a
/dev node to be able to handle the device, therefore the kernel must do the
work up to that point.

We've made a business out of making money from annoying and stupid people.
I think you fall under that category.
