I don't know about Stuart, but if I had to incorporate someone's text into my LaTeX document, I'd much prefer plain ascii over machine-generated LaTeX. Machine-generated LaTeX often has all sorts of exotic macros to get it back to something WYSIWYG. If you don't have tons of math or similar, it costs maybe 15 minutes to get 30 pages of ascii text properly formated. Since you don't have to micro-manage, it's just down to inserting a control structure into the text.
I want to give you something formatted better than a plain-text ASCII document
I do appreciate the sentiment, but in practice it probably means one has to take all formatting out of your text to get it back to ASCII, then put the LaTeX formatting back in to comply with the rest of the manual style. So it may not be as helpful as you think.
