Blip,
I don't disagree with your position. However the data is available. If your company chooses not to publish it in one form or another, why don't you approach your performance people to get access to the data on a one-off basis and then you have the comfort you seek for your own flight planning. Do keep in mind that there is a range of variants for these aircraft and you need to make sure that you refer to the correct set of data.
Certainly, one airline for which I flew provided such data to operating crews ...
