Ok. How about my laptop? I have an ATAPI zip drive I can plug
in instead of a second battery. It is the only device on the
second IDE bus (hdc). In windows there is a little hotplug
utility thing one runs before unplugging the zip drive. In Linux
I currently have to reboot if I want the ide-floppy driver to see
the device... I'm willing to bet that Dell has done mysterious
stuff to make the electrical part work. It would sure be nice if
I could ask the ide driver to kindly re-scan for /dev/hdc now.

Is whatever windows is doing when I hotplug my zip drive somehow
unsafe, such that supporting the same functionality on Linux is
somehow a Bad Thing(tm)?
