I thought of that, several reasons not to:

1)  There's a good use case to allow nesting one deep.  There's no 
similar use case for multiple levels of depth.  (If you have one, let me 
know).
2) Ordering becomes complicated if you allow multiple levels of depth. 
Complicated is bad - this proposal is already complicated, but no more 
than absolutely necessary.
3) We can always add it later, but cannot take it away if we add it now.
