Bob, A fuss? No more then that about K10D, K1D, K20D, etc... :-) Well... 1. The articles in question demonstrate these conclusions based on solid optics-based evaluation of the drawings. The authors methodically analized many paintings, and concluded that _many_ artists must be using lenses+tracing. 2. Apparently, some researchers do not agree with the conclusions Hockney and Falco make. As far as I can tell, the biggest opponent is David Stork, whose multiple publications where he is objecting the conclusions of Hockney and Falco (IMHO too aggresively). It shows that it is far from being accepted unanomously.
