Objectively the route would be safer if a hold that is "on its last legs" were removed.
I presume you do not know Von T and their ability to assess the stability of a hold. To me they are a random person posting on a public internet forum - could be anyone. I do not know whether they predominantly climb sport or trad, frequent Craig Doris and Cilan Main.
I have frequently seen chalked X’s on blocks that would require a crowbar to remove. “Last legs” is an entirely subjective comment.
I would not even hint at removing a block on a public forum without wanting to see it for myself.
