I am not sure about work that was 'left' (or attempted in the past) but 
I assume you have checked our issue tracker? (although a lot of the open 
issues are to do with musicxml2ly than anything else.

At first blush I'd say no. However I have only been with LP for ~ 6 
years and cannot recall anything in that time, but there may have been 
some work done previously, but I cannot see any 'abandoned' issues 
either - where you may see some remnant of previous work/patches.

Also see:

https://sourceforge.net/p/testlilyissues/issues/665/

Which may have some of the kind of answers/information you might be seeking.
