It has always been the case. Attending IDC in 1999 before a single device had been certified and the hardware standards and certification docs were already 3500 pages. You can only imagine how this has grown in 20 years. Bluetooth is a "giraffe" technology. It evolved in to the current form through happenstance. Nothing about it is simple or normal, instead randomly weird and inconsistent. And nobody is surprised that after 20 years everyone rightfully assumes that it barely works and is full of holes. However, since the standards are controlled by the people who build the hardware it is not been possible for a functional, non-insane alternative to appear.
