I agree with all you said (except some little points I will develop under)…still, I believe that it is not easy to do: if you were to present da,ti,na applications for a single tech, and along with that a two-man drill that as you excellently plointed out can be devised from the techs, it would make at least like 5-6 pics of applications for a SINGLE move…the number of pages can increase REAL fast. If you skip the history, some people will complain, if you skip the training methods, some people will complain, and so on and so on…I believe, and it’s just MHO, that it is impossible to make a perfect gong fu book…even the best book out there (about which many people will disagree when it’s time to vote, trust me) will lack something…this missing part might be crucial to you, and not to the next guy…
OK, what I disagreed mostly with was about elitism…WE HAVE TO BE ELITIST…it’s WAR arts we’re talking about…not anybody can learn to fight for real (let’s forget about P.C.).
You see how many fighters of other styles scoff at us and kung fu already?? If we are not pointing towards a ceratin kind of elitism it is going to be even worse…good gong fu was never and should never be a mass product (don’t get me wrong, there are schools with many students still producing very high gong fu). Real gong fu, even in modern, big schools, is demanding. Even though it has spread in ways the elders never imagined thanks to modern communication, it remains an elistist art deep inside. You have to suffer…sweat…sometimes bleed. Dedicate a lot of your time and money, give up a part of your social life even…you can’t acquire true gong fu by being a sybarite and bumming around, or unwilling to invest anything…in the end, good gong fu is elistis. To me, books and videos are wonderful tools to sensibilize the masses, and preserve some of the art. But eventually you’ll have to learn from the master, it’s all that counts. The book, IMHO, are there to draw persons to the art, persons that have what it takes but might never have heard of the art or a talented master if it weren’t for the books…
Books are like boats…once you are across the river, you don’t need the boat anymore, however useful it was during the cruise…I would be very disapointed if a master was to give all his tricks in a book…I don’t even think it’s possible, since the tricks usually need man to man teaching…sure, he can mention it in a book, but it’s quite useless…to me, a good master need to keep some full clips…unloading everything in a book would be a bad idea for gong fu. To me, gong fu is something you have to deserve…gong fu doesn’t come to you, you have to come to gong fu…
Then there’s the history research…it doesn’t improve your fighting at all, but God how sweet a pastime that is 
Thanks for your time, and sorry for the lenghty blah blah
