My view is, it's no loss if no one gets it, and if someone does, the resultant discussion is mostly useful for the serious practitioners, so I see it as a win-win.
Twenty years ago, people were teaching forms they had never really studied the style of. When the focus is technique level discussion, this kills the ability of such shenanigans, and the people who tend to steal form as such also tend to not be able to attract good training partners so that, when technical discussion is available, they are unable to entrain it with a partner. Further, by being open with technique level discussion, one ends up being more open to examining variations, which gives people room to test ideas out who maybe aren't as confident in their knowledge, but do have some knowledge.
As it stands, technique level discussion would improve the overall level of kung fu, and certainly not diminish the ability of the best.
