Wasn't the pager invented for sifting through output which has to be

In fact, -D would be quite analogous to -M and -C in that respect.
There is a big difference: -M and -C lets your recipient reproduce the
state using the change you are trying to convey with the diff output in
either direction (iow, "apply -R" works), but your "-D" would not have
that property.
