Don't mistake disagreement with your scenario as "limiting the possibilities". What possibilities does this bring to the party that do not already exist? Some cheaper method of using one piece of gear for both diciplines? What is profound about that? What is so thrifty about that? I can, and have, rented a Canon video camera and used my L lenses to do test commercials. The difference is a non-issue. The client could've cared less what I used.
BTW, guess where almost ALL TV test commercials are now shown to consumer target groups ... the internet.
Digital still photography was profoundly different as far as commercial applications are concerned. IMO, this isn't.
People may well flock to it, and the garbage will pile up.
