Acting for the theatre is different from acting for the screen. Since an onstage performance needs to be readable by the entire audience, thespians project more broadly. OTOH, film allows the actor to be more nuanced in her performance since their actions are more easily read by the camera. I believe this is what the parent poster intended with their comment about the "unnaturalness" of the theatre.
The technique of rotoscoping is not restricted to tracing of live action footage; it was not disinformation on Disney's part to describe the process employed as "modelling".
Slavish obedience to live action film reference (i.e. direct tracing) actually produces a mechanical, stiff look in animation (For examples see Bakshi's "Lord Of The Rings", or more recently "Final Fantasy"). However, when used as reference to be supplemented by an animator's skill and understanding, rotoscoping can be a useful aid.
Thoughts on the "replacement of actors by CGI": Fundamentally, the animator is an actor. He/she has to submerge himself into the mindset of the character being drawn/modelled to create a convincing performance. It seems silly to claim CGI as the death knell of acting - rather, CGI will constitute a new medium for acting. Film didn't eliminate theatre; CGI won't eliminate acting.
Actually, Topsy was due for an execution by hanging (she had killed three people in as many years), but there was public concern over the inhumanity of hanging her. Edison stepped up to the plate with the intent of a) making AC power appear dangerous, and b) demonstrating the effectiveness of electrocution as a painless form of execution.

In creating "Snow White", live action footage was NOT traced. Rather, the footage of live actors was employed by animators as a starting point for creating key frames (extremes of position), and inbetweens were subsequently drawn without reference to the film.
