An economic viewpoint on your first question is that there is not enough margin (or energy, leverage, etc) left in the system level ecosystem to press for the need for a standard. In the old days Compaq etc very strongly pushed for standards to help them PCs move away from IBM. This began to come undone around the time of EISA, which was ratified but failed, and PCI, which was Intel sponsored. It only got worse after AMD (and other x86 semis) lost ground to Intel.
