Even something like this is a lot more complicated than it sounds due to
the fact that several operations can be happening in parallel.  I think
we just need to draw a line for Nova that just doesn't include this

Right, remove is straight forward, but seems a bit odd to have without
add.  I'm not sure there's much value to it.
