I do not know. Probably historical accident: somebody wanted
to do things in different way and left a half-baked code.
It makes sense to have a convenience function which produces
latex on demand, but for this it is enough to add it to
'CoercibleTo(OutputForm)' implementing it on top of coerce
and TeXFormat. Or add a tiny package.

That looks very good. Of course we need to adjust efricas and
MathAction. For MathAction I hope this will be easy: AFAICS
Python code matches generically '\begin{something}...\end{something}'
so probably no change will be needed. There is global LaTeX
template and we need to use apropriate style there. MathAction
uses texbreak program. so the main question is how breqn compares
to texbreak.
