ARC review is only to cover speed and size issues when they are large 
enough to have some architectual impact.  In my estimation, these don't 
qualify.

I agree that this isn't an architecture issue, but its not just rust.  
At about nv60, the GUI installation died on 512 mb laptops because the 
miniroot couldn't run (in gui mode).  Its not an architectual concern, 
but it is a practical concern.
