   > I have one question though, I would like to understand better. Couldn't we 
have done a version that works for any level of nesting of lists? I wouldn't 
want to see a 'need to support 4 level lists' in the future. Not grounds to 
block this PR, we can always revisit if needed and given there will be a config 
flag from now on, easy to enhance later.
   
   Thanks for the review!
   
   I actually don't see a reason for having more level of nesting. The three 
level nesting was needed to support nulls at all levels of list definition. 
Moreover, this is how other models have it implemented as well.
