Hi Nicolas,

> *snip lots of text*

Thanks for going through my points in detail. I think I understand your
perspective much better now. At this point though, I’m not really sure what to
make of `\[ ... \]', I now feel like it’s sitting in some sort of markup limbo
where it can’t be either fully LaTeX-y or fully Org-y. I still think it would be
good to improve this, but I no longer have such a firm idea that “modifying fill
is the way”.

All the best,
Timothy
