Yes, to some degree, which is partly why I hadn't used org-latex-preview
until recently.
I have thought about using overlays of unicode math glyphs to achieve
something similar to org-latex-preview. E.g. overlaying ∫ on \int, ₀ on
_0, etc.

I have not tried to publish papers with such formulae, but I think with
the recent changes in texlive, it should be possible soon. On the other
hand, overleaf does not have good support for such formulae, so maybe
not so soon.
Mainly, I use this style for my lecture notes.

Thanks for the suggestion, I just tried it on a small math document and
the results are quite good. It is even in the "texlive-latex-extra"
package in debian, so it was already on my hdd.
