Good point.

Actually, it is not that much hard. At least, it is not that hard for
paragraphs.

The linked discussion had other caveats involving whether
special filling is even reasonable for the discussed elements
(AFAIR).

However, org-fill-element actually does have a special treatment for
line-break objects inside paragraphs. There is nothing preventing us
from special treatment of other types of objects in similar fashion.

In fact, we may even utilize Emacs built-ins for page break symbols
specifically. Just use fill-region instead of fill-region-as-paragraph.
Similar to https://orgmode.org/list/875yhiyxnb.fsf@localhost
It's just that I am not sure about other possible side effects of such
change.

P.S. Does LaTeX understand ^L?
