just me and a preference to err on the side
of caution when dealing with devices that might
alter a very basic thing.

maybe, if they just want to see what it says
it will do.
also, consider that bugs do happen and sometimes
a dry run switch will discover them before it does
the actual write to the device.

yes, always a good idea.
mostly the idea is to prevent "wrong device" or a fumble
finger kind of error. with some things i know it is ok to
ask for forgiveness instead of asking for permission, but
when it comes down to devices and partition tables i put
them in the more paranoid group.
