So you stop users being able to hotplug controllers while doing firmware
updates. Thats not good either

Fedora bugzilla has demonstrated it *doesn't* work. There is a long list
of broken third party apps such as drive firmware tools many of which will
never include source code. The whole point of sg is arbitary management of
devices. Its like /dev/mem and so forth, its power is in the fact it can
always be used. This is why Linus vetoed the entire concept.

Fedora hasn't solved the open /dev/sg , insmod case either.
