I don't think any of the solutions do help you to write to a raw device,
whether it be a floppy or a USB stick. Writing a Debian ISO to USB is
not uncommon here and I do not appreciate having to be root to do it. A
mistake in one letter in the command could ruin your day.

Those who do not have root privileges don't even have the opportunity to
wipe their hard disk, or dd an installation image to a removable device
to pass on to an interested friend. If the thinking behind the change
had been *explained* one could be more sypathetic to it.
