Mentioning `prettify-symbols` was not necessarily about changing it,
but an argument in favour of valuable functionality, because there
is also the school of thought stating that built-in tex-mode and
latex-mode should only implement the most basic functionality (e.g.
language highlighting) rather than including convenient tools such as
typography previewing and keyword shortcuts (e.g. cdlatex).
I am more pragmatic, seeing typography previewing and keyword shortcuts
as valuable even for a basic core tex and latex mode.
But not extreme, in the sense that Auctex can continue as a package
for additional functionality.

It is the plan to provide keyword shortcuts to tex-mode and latex-mode without
a built-in mechanism (taking code from texmathp.el or otherwise).
I do not approve that auctex should automatically take over. On the
contrary, auctex is a separate project, and in accordance with that,
a user should specify whether he wants to hook with the emacs built-in
or with the auctex ones (e.g. auctex-tex-mode, auctex-latex-mode,
auctex-tex-mode-hook, auctex-latex-mode-hook). Consequently one can
simultaneously allow some files to use latex-mode, whilst others can use
auctex-latex-mode.

Duplicate the functionality, although we can duplicate the code
because its author Carsten Dominik allows us. We can then return
him a cleaned-up version that he can progress further if he wants
as a separate project.

I do not see it would be a big challenge with users to simply change to
auctex-tex-mode and auctex-latex-mode. We can keep them for a while, but
they stop taking over all tex and latex files when one wants to use latex-mode.

Right, we should do the same with the built-in tex-mode which mixes
the tools fol tex and latex in the same file.

If auctex is not doing anything smarter that what we have with
