Yeah, luckily, nobody expects such. I do not think any of our document says nothing other than HEAD like CHERRY_PICK_HEAD is reachability anchoring point; they are designed to be transient.

Because they are designed to be transient, I do not think there is any downside (other than the initial start-up cost) to including them in reachability computation. Because they are meant to be transient, the objects anchored by them would be reachable from other anchoring points anyway.
