Interesting idea! I will pass it to my friend Andrea Arcangeli and 
report back to the list...

 From an utterly practical point of view, any change in this area would 
imply adding non-trivial configury bits, since many 64-bit platforms 
don't provide yet the ideal "unlimited" address space (see my exchange 
with Dhruv about linux on x86_64 and 4level page tables).
