I think there are 2 kinds of "prune"s that might be treated differently:
o C o C
x B (B -> (), parent A) | x B (B -> (), parent A)
o A o A
When pulling "C", I guess it's reasonable to pull the marker for the left
case. The right case might want an option.
Practically, it's doable by ignoring the "parent" field in markers.
