I am not saying you should, or shouldn't. Just that it's _usually_ not
necessary. Again, it's window based. Like you said, if you got the window,
go option 21 is the most complete. But that does not necessarily make it the
most reliable or the best  for every situation. In an ideal world, well,
everyone would have a full T1 or better and replicate to a mirror site in
another state, far, far away and recovery would be switching a TCP address.

Yeah, after considering that for a moment, I can also see some situations
that it might be a concern... if someone is ftping a file to your site and
you process it and then delete it, you don't want to re-process it if it's
in the data of the other restores. I have a client that this happens with,
but they are all isolated to a single library for inputs and when that
library is restored, it is reviewed prior to restarting the systems. And,
yup, that's written down for them.

Again, that's why planning is important and understanding the particular set
of circumstances and restrictions that one would have. And my aversion to
the blanket comment that one should do it "this way".
