Right, it is removed because all the PSHed packets are acked as soon as rcvbuf is completely drained and window is full open.
See? It is the reason of "too frequent" ACKs and I daresay they are not too frequent and it is impossible to do something with this. These ACKs are an _absolute_ demand and delay by some small time helps nothing destroying performance instead.
Well, it is the place, commented with "Dubious? ... final cut." It is enough to delete it to avoid "too frequent" ACKs and to return to too rare ACKs instead.
