Yes indeed. I am quite aware of difficulties involved. I did myself a
small [[https://github.com/amno1/dired-auto-readme][hack to dired mode to "auto 
show" readme files]], and got into all
those problems there.

That one major mode per buffer is starting to be a limitation. What we
really would need is a major mode per region, or some other mean to be
able to combine modes. Maybe something like a "primary mode" which would
be what Emacs opens into when a file is loaded, i.e. 'org-mode' in this
example and secondary modes, which would be other major modes loaded,
and somehow activated per region or I don't know. But that is a
day-dreaming :). It would require rebuilding entire machinery.

Yes I know. I tried with mmm-mode, didn't really work well for me.

Haha, definitely :-). But that is the story of my entire life ;-).

Yes, in this case, that is correct. What I am doing here is bending
entire org-mode to do something it is not supposed to do. If you are
interested you can take a look at 
[[https://github.com/amno1/.emacs.d/blob/main/init.org][my little app on my 
github]]:

Look at "org hacks" under generator heading.

That is what is hapening, but I started this as a hobby project as well
as a learning experience. I really suck at both Emacs internals and
elisp, so I need something like this as a learning project.

Thanks, and thank you for the tips and feedback.
