Nice document @ Andre. Thanks for sharing.
I will open a sticky where we can save all those useful links and documents in PDF.
RC is just one way to implement the deflection and decoupling principals really. It works for sure, but when facing the reality of construction sites and the complexity of some (well, most) structures - for example complex, angled, wall sandwiches which are further loaded with internal acoustic treatment which is anchored to it or needs to be anchored to the sub-structure - shows that in a majority of cases, the efficiency of those solutions decreases rapidly, they sometimes become more of a constraint than anything else really.
Not that they don't work, they do, but add a grain of salt.
