Does anyone else find the current state of the world confusing at best?

Yes.

Another suggestion would be to (always) print:

     Estimated space to be consumed:<small>  (<big>  peak)

though I kind of like the idea that peak usage is only printed when the
plan would fail, so you know how much space to free up.  If we always print
it (alongside the extra final number), then people might try to divine the
correlation between the two, even though that's a deep, deep implementation
detail.

Another thing to consider -- on a change that reduces the amount of
diskspace used, would we print a negative number?

Because of zfs snapshots; no.

As Bart also pointed out, there's de-dup, compression, etc. to consider.

So it's best to simply ignore removals.
