Didn't know they had gone and borrowed a TfW set? Is fairly sure they are the shorter Mark 4 formation.Sadly they'll all be short formed.
But less flippantly, the options were 91 + 7 + DVT or more 5 carriage IETs (and/or fewer services). If the former is 'sadly' then I take it you think the latter would have been better?
