yeah, essentially, attend the cut if you are that worried, otherwise you are signing over some decision making to the engineer.
Anyone who regularly produces for vinyl should know about the difficulties with top end, so really you should have factored this in yourselves, or at least put some kind of notes to the cutting engineer, that you wanted the top end toppy as it was. Assuming you`ve used lawrie, he would have gone for his standard (and generally damned good) loud and pumpy cut, which you should have known anyway, so you were bound to lose any over crisp top unless you attended or told him otherwise.
However, I also thought the TP stage was the chance for you to say, oy, not appy with that, can you sort it.

So a bit of careful negotiation is obviously needed here.
