Yes. It's not THAT uncommon that I'll boot a laptop for the sole purpose of
reading data from a USB stick and I expect that others do the same.
Also there's the possibility of booting a laptop/netbook from a USB stick and
then using an encrypted root device. This prevents an attacker who has
temporary access to the system from subverting the boot process on disk, the
attacker could still subvert the BIOS but that's more difficult. In the case
of such things you would have the USB device seen early in the boot and then
removed during the boot process.
Anyone who reads Planet Debian would have seen the above two posts I wrote
about using USB flash devices for all storage in a system. While that is an
unusual use of a system it's really nice if we can make things just work so
that the user gets a full range of choices about how their system works.
While I don't expect that the kernel and udev developers and package
maintainers (who are really very busy) would go to extra effort to make my
particular corner case work I'm sure that they are quite happy that their good
work results in all manner of unusual corner cases just working for various

Every version of Debian is released with some bugs, it's the way that software
development goes. If the worst bug was that plugging a USB stick at the wrong
time could disrupt the boot then I think that most people would consider it as
ready for a release.
The real problem is when people start claiming that such things aren't bugs.
As an aside, my monitor has some sort of SD card reader built in. I've never
used it but it registers as a SCSI device. This means that the order of
switching on my monitor and inserting a USB stick affects what the device name
will be. With a static /etc/fstab this doesn't work too well for me.
Hopefully I will find a better solution.
