That's the asumption of most designers, and it's not hard with
continuous text like a novel, where every page is identical, but
definitely problematic with anything else.
One critical thing to avoid in metal type is show-through, where the
impression of the type on the reverse of the paper is visible. One way
to minimise this (in addition to employing good press operators) is to
make sure that the lines of type on one side of the paper line up
EXACTLY with the lines on the other side. It's also true in modern
(litho) printing, of course: even though it doesn't indent the paper,
you still need to minimise the darkness being visible when you are using
paper that isn't very opaque.

I had to do it for display math once, so I invented an environment which
set the equation, measured it, and output it vertically-centered in a
vbox to an integer number of lines. Not elegant, but it helped.
