except that the former IMHO better suits the definition of memory
region, which I see as a single contiguous range of memory and can be
simplified to have a single reg entry per region.

My point is rather if multiple reg tuples are found in a reserved memory
node, the kernel must respect them and reserve the memory. I'm not
arguing about whether or not that makes for a good binding.

agreed.

My point is why, if the binding defines that just a single tuple should 
be provided.
