Ah, I see your point, and the commit message was clear:

    This commit is similar to commit 8a879119, which taught nbtree to
    use fake LSNs to improve its dropPin behavior.  However, unlike that
    commit, this is not an independently useful enhancement, since hash
    doesn't implement anything like nbtree's dropPin behavior (not yet).

Item removed.
