The reason it tells you that data will be destroyed is that that could

Like Jeff said, this is not a recovery tool. It's certainly not meant
to be something that you keep turned on for any length of time, and so
the possibility of repeat messages is really not a design consideration
at all.
No argument with any of this, although I'm not the intended audience for
these warnings -- I know what I'm doing ;)
I'm not sure though if you're disagreeing with my
suggestion that the documentation be improved/corrected though.
Is that the case ? (if so then I will argue)
