It used to be quite normal for a wb on the trenching and was commonly requested by the DCs. It seems to becoming more frequent for the contrary. As for costs, that shouldn't be the concern of a curator but for a representative of the client. However, I would concede that may depend on the nature of each individual project but, as you say above, each evaluative technique can't give you a complete picture.
