This works just fine and is probably for the best in any case. Using a
latex block allows for latex specific editing (C-c '). Should have done
this in the first place!
Technically, this isn't the same. The LaTeX block would be removed
during an HTML export while the plain LaTeX code would be changed into
an image (or Mathjaxified, whatever that means).
Agreed. For my use case, this is not a major issue, mind you, as my
preferred export route is to PDF via LaTeX...
That's annoying because I tend to think that writing plain LaTeX
environments (without any block marker) should be deprecated.
Again, agreed, but this will require a more general approach to the
handling of e.g. latex blocks for export to other languages. Not easy,
I would guess, unless we make more use of conversion to png for blocks.
Thanks again,
eric

Therefore, there's no urgency in addressing this bug.

I understand your concern, but, as far as I can tell, that's not a bug.
Lists have precedence over LaTeX snippets. In other words, you're asking
to start a list here, and Org starts one.
Also, that this kind of line won't appear automatically[1] (during
filling), so Org assumes it's here on purpose.
Regards,
[1] Now, if it does, that's indeed a bug.

That's annoying because I tend to think that writing plain LaTeX
environments (without any block marker) should be deprecated.
Indeed, while there's a need for short mathematical LaTeX snippets,
LaTeX environments can imply constructs that :
- are not always related to mathematics (and should therefore be
handled by Org blocks)
- are too large to be called snippets (and should therefore be
handled by Org blocks)
Also, I don't know what to think about an object that you can inline on
the right side but not on the left one (and I admit that's what annoys
me the most, at the moment).
