Hi Nicolas,

I understand that org-mode is not LaTeX and therefore the org-mode
internal representation of LaTeX should not matter to end users like
me. That's fair enough. In the end of the day the reason why I started
looking into this is the fact that I do not find user friendly that
org-mode, when filling a paragraph, interprets \[...\] as any inline
snippet and does not keep it on a separate line (as recommended by the
LaTeX manual, see attached document). That's it.
I've therefore started messing around with
org-element-paragraph-separate, but after a while I thought that it
would be better to look at how the \begin...\end environments are
handled and try to do the same with \[...\]. That's how I noticed the
difference between the two (and perceived it as wrong handling of
\[...\]). I just thought that correcting the filling behavior of
org-mode would be useful to all users of org-mode and not just me.

In any case, if it's just me, I would greatly appreciate an advice on
how to achieve my goal from somebody with a good understanding of the
internals of org-mode. Is there a better way than just changing
org-element-paragraph-separate?

Thank you in advance for any advice.
Best Regards,
Fede

P.S.: I've attached for reference two pages, from the book written by
LaTeX's creator (the book I've mentioned on my first email), on how to
use the various mathematical constructs.
