I don't see how this would help the prune/remove situation?

For instance, if you start a pull operation, and it enumerates all
objects it needs, skipping some that are already installed. But after a
while a prune job starts, which does not see the new ref, so it will
remove objects that are not referenced by others refs. This can end up
removing the objects that the pull assumed was already downloaded.
