Point taken, I sometimes (ab)use the auctex mailing list as a general
list for editing latex files in (X)emacs, which would include reftex,
cdlatex x-symbol etc.

I also thought that the issue of sub and superscripts is a general
feature of GNU emacs, however in the context of latex files it is the
most relevant, but now I understand that the super subscript issue is of
more special character as the following paragraph suggests.
Or in other words it is not possible in general to make the _ and the ^
disappear, which is sad and ugly.

Right, what I miss most know is the inverse function of

I tend to disagree, see my comments below, however I agree: a inverse
function to  latex-unicode-simplified would be convenient.

As for AUCTeX fold mode: first of all in Xemacs it does have the
features that are present  in GNU emacs: replacing (using overlays?) math 
constructs such
as \int really by its (unicode?) Symbols.

However I consider the fold mode as being  inconvenient. When
I modify a formula I have to toggle all the time
