BS !!!!!!!!  it is time you actually looked at the history and realized that
there is no satisfying the routing side of this problem space. The original
design was 64 bits in total, but the routing world couldn't find enough room
for themselves if they allowed any space for those pesky end users, so the
design was revised to give the entire 64 bits to routing. We argued for
quite awhile about how many more bits to add for hosts, and after picking 64
to align with emerging cpu widths found it was possible to allow simplified
addressing using slaac. 

Fast forward, and at every turn the routing community whines about 'waste',
yet they are not able to actually deal with 18,446,744,073,709,551,616 entry
RIB's, so giving them more bits is the real path to waste. Get over it...
