So if one thousand years from now, after all other records of our era had been destroyed, somebody stumbled across an internal memo from a utility middle manager to his superior apologizing to his supervisor and then compared it to by Vonnegut or maybe by Tolstoy, would they be able to tell what style was typical of the period? For that matter, if they only had Vonnegut and Tolstoy what comparisons could they draw?

I realize this doesn't really dispute your conclusion but, without having read the articles you linked, it doesn't seem like there is enough information to draw much of a conclusion here.

That being said, it is fascinating stuff.
