If it is just a test go ahead without /boot partition and whatever else you
like to try. For a production system besides considering "whatever works" I
would also consider how much effort and time I would have to invest if
something goes wrong. How fast can I have the system back online and in a
usable state. That may totally change the picture.
Murphy's law: If you provide for two different ways in which something may
fail it will fail in a third and totally unforseen way.
