Could you tell us where that discussion takes place?

I also want some improvements with regard to the "integration" because I
recently realized that emacs built-in `tex-mode' (accidentally?) shadows
AUCTeX `TeX-tex-mode' since emacs 28.1, to fail to enter LaTeX mode for
some cases[1][2]. (I'm not sure that the above discussion involves this
issue.)

It basically looks reasonable. I assume that you are thinking that
`AUCTeX-mode' actually chooses suitable behavior according to the value
of `major-mode' between `latex-mode', `plain-tex-mode', `doctex-mode'
and `texinfo-mode'.

Here are some random thoughts.
1. There will be some overheads because it first runs initialization
codes of emacs built-in mode and then runs AUCTeX minor mode; I expect
that the associated cost is cheap enough.
2. AUCTeX still must retain some major modes, i.e., ConTeXt mode,
AmS-TeX mode, Japanese LaTeX mode and Japanese plain TeX mode because
there are no counterparts in emacs built-in modes.
3. Currently, there is defect in handling doc strings of AUCTeX LaTeX
mode, plain TeX mode and docTeX mode; C-h m and C-h f show doc string
of built-in modes, not AUCTeX modes. `AUCTeX-mode' should put suitable
`function-documentation' property for the respective major mode symbol.
4. `TeX-tex-mode' and `tex-mode' would need some special treatment.

From the users' point of view, I don't think it matters much. They just
specify
%%% mode: latex
as the file local variable and think that they are using `latex-mode'.
I think that it would be only Elisp programmers that care about the
"lies".
