It seems to me now that "technical diving" is a moving boundary that separates few divers from many divers (see above: nitrox, rec trimix).
It is not a fixed form of diving. It is a subgroup selector. It is constantly redefined to define an elite.
Trimix is technical now, but if too many use it, it becomes recreational.
