Every conference has their own required LaTeX style file that must be used. Unless there is an automated way to convert these exactly, I don't see how LaTeX alternatives can be used.
This is a general argument against any sort of innovation in this field, which is absurd.
Is LaTeX difficult to learn? An article stated something about how its syntax is inscrutable, from what memory will allow before the caffeine hits.
I think that might be true at some maths and computer science meetings but is unheard of in other scientific fields.
