No, there is no plan to support deeper nesting (not on our side anyway). 
As you wrote, the current mapfile structure (and the Map object 
structure in memory) wouldn't be well suited for that. And going to an 
XML map file format without changing the map object wouldn't help for 
that either. (However something could probably be done using metadata 
without changing the object structure I think.)
