I do not say that there is no tests, but to change the parser almost 
certainly much more corner cases should be added. The format should be 
suitable for non-elisp tools.

I expect that pandoc-like parser may reduce number of pitfalls. However, 
having no experience with parsers, I will unlikely try to implement it. 
I would not be surprised if it is unfeasible without some parser 
generator since it should be bottom-up one. I have no idea how to 
collect real life cases when current behavior is better. Otherwise it is 
hard to estimate degree of disaster due to breaking change.
